tests: pin ink engine in _make_tui_argv npm-bootstrap tests (post-merge semantic fix)

Main's rewritten test_tui_npm_install.py tests call _make_tui_argv expecting
the Ink/npm flow unconditionally; with the dual-engine dispatch merged in,
_resolve_tui_engine() auto-selects opentui whenever ui-opentui/dist is built
in the repo, routing the call away from the path under test (first subprocess
became 'node --version' instead of 'npm run build'). Pin the engine to ink
via an autouse fixture, mirroring the existing pinning precedent in
test_tui_resume_flow.py.

+# Photon iMessage platform plugin
+
+This plugin connects Hermes Agent to iMessage (and other Spectrum
+interfaces) through [Photon][photon] — a managed service that handles
+iMessage line allocation, delivery, and abuse-prevention so users don't
+have to run their own Mac relay.
+
+The free tier uses Photon's shared iMessage line pool and is the path we
+recommend for everyone who doesn't already pay for a dedicated number.
+
+## Architecture
+
+Like Discord and Slack, Photon is a **persistent-connection** channel — no
+public URL, no webhook, no signing secret. The `spectrum-ts` SDK holds a
+long-lived **gRPC stream** to Photon for both directions. Because the SDK is
+TypeScript-only, Hermes runs it inside a small supervised Node sidecar and
+talks to it over loopback.
+
+```
+                         gRPC (spectrum-ts)
+┌─────────────────────────┐ ◄───────────────► ┌──────────────────────┐
+│  Photon Spectrum cloud  │   app.messages    │  Node sidecar        │
+│  (iMessage line owner)  │   space.send()    │  (plugins/…/sidecar) │
+└─────────────────────────┘                   └──────────┬───────────┘
+                                       GET /inbound (NDJSON) │  ▲ POST /send
+                                       inbound events        ▼  │ /typing
+                                              ┌──────────────────────┐
+                                              │  PhotonAdapter        │
+                                              │  (Python, in gateway) │
+                                              └──────────────────────┘
+```
+
+- **Inbound**: the sidecar consumes the SDK's `app.messages` gRPC stream,
+  normalizes each message, and streams it to the adapter over a loopback
+  `GET /inbound` (NDJSON). The adapter dedupes on `messageId` and dispatches
+  a `MessageEvent` to the gateway. It reconnects automatically if the stream
+  drops; the sidecar owns the gRPC reconnect to Photon.
+- **Outbound**: `send` / `send_typing` are loopback POSTs to the sidecar,
+  authenticated with a shared `X-Hermes-Sidecar-Token`.
+
+## First-time setup
+
+```bash
+# One-shot setup: device login (opens browser) + project + user + sidecar deps
+hermes photon setup --phone +15551234567
+
+# Start the gateway
+hermes gateway start --platform photon
+```
+
+`hermes photon setup` does, in order:
+
+1. **Device login** (RFC 8628, `client_id=photon-cli`) — opens
+   `https://app.photon.codes/` for approval and stores the bearer token.
+2. **Find or create** the `Hermes Agent` project on the Photon dashboard.
+3. **Enable Spectrum**, read the project's `spectrumProjectId`, rotate the
+   project secret, and persist both.
+4. **Register your phone number** as a Spectrum user (idempotent — skipped if
+   a user with that number already exists).
+5. **Print the assigned iMessage line** — the number you text to reach your
+   agent.
+6. **Install the sidecar deps** (`spectrum-ts`).
+
+There is no separate `login` command; like every other Hermes channel,
+onboarding goes through one setup surface. Re-running `setup` reuses an
+existing token/project, so it's safe to run again to finish a partial setup.
+Run `hermes photon status` to see what's configured.
+
+## Credentials
+
+Runtime SDK credentials live in `~/.hermes/.env` (the same place every other
+channel keeps its token), and the adapter reads them from the environment:
+
+```bash
+PHOTON_PROJECT_ID=<spectrumProjectId>   # the SDK's projectId
+PHOTON_PROJECT_SECRET=<projectSecret>
+```
+
+Management metadata lives in `~/.hermes/auth.json` under `credential_pool`:
+
+```jsonc
+{
+  "credential_pool": {
+    "photon": [
+      { "access_token": "<device-bearer>", "issued_at": ... }
+    ],
+    "photon_project": [
+      {
+        "dashboard_project_id": "<dashboard id>",
+        "spectrum_project_id": "<spectrumProjectId>",
+        "project_secret": "<projectSecret>",
+        "name": "Hermes Agent"
+      }
+    ]
+  }
+}
+```
+
+> **Note on ids.** A Photon project has two identifiers: the dashboard `id`
+> (used for management API calls) and the `spectrumProjectId` (what the SDK
+> authenticates with). `PHOTON_PROJECT_ID` is the **spectrum** id.
+
+## Configuration knobs
+
+All env vars are documented in `plugin.yaml`. The most important:
+
+| Env var                   | Default                    | Meaning                              |
+|---------------------------|----------------------------|--------------------------------------|
+| `PHOTON_PROJECT_ID`       | from .env / auth.json      | Spectrum project id (SDK `projectId`)|
+| `PHOTON_PROJECT_SECRET`   | from .env / auth.json      | Project secret                       |
+| `PHOTON_SIDECAR_PORT`     | 8789                       | Loopback port for the sidecar        |
+| `PHOTON_SIDECAR_AUTOSTART`| true                       | Spawn the sidecar on connect         |
+| `PHOTON_DASHBOARD_HOST`   | https://app.photon.codes   | Dashboard API host                   |
+| `PHOTON_SPECTRUM_HOST`    | https://spectrum.photon.codes | Spectrum API host                 |
+| `PHOTON_HOME_CHANNEL`     | your number (set by setup) | Default space for cron delivery — a space id, or a bare E.164 number (resolved to a DM) |
+| `PHOTON_ALLOWED_USERS`    | your number (set by setup) | Comma-separated E.164 allowlist      |
+| `PHOTON_REQUIRE_MENTION`  | false                      | Gate group chats on a wake word      |
+| `PHOTON_MAX_INLINE_ATTACHMENT_BYTES` | 20 MB           | Max inbound attachment size the sidecar reads & inlines |
+
+## Attachments & limitations
+
+- **Inbound attachments and voice notes are downloaded.** The sidecar reads
+  the bytes (`content.read()`) and base64-inlines them on the NDJSON event; the
+  adapter caches them to the shared media cache and populates `media_urls` /
+  `media_types`, so the agent sees the real image/file or can transcribe the
+  voice note — parity with the BlueBubbles iMessage channel. Media larger than
+  `PHOTON_MAX_INLINE_ATTACHMENT_BYTES` (default 20 MB), or any byte read that
+  fails, falls back to a text marker (`[Photon attachment received: …]` or
+  `[Photon voice received: …]`) so the agent still knows something arrived.
+- **Outbound attachments are supported.** Images, voice notes, video, and
+  documents are sent via `space.send(attachment(...))` /
+  `space.send(voice(...))` through the sidecar's `/send-attachment`
+  endpoint; a caption is delivered as a separate text bubble after the media.
+- **Reactions, message effects, polls** — supported by `spectrum-ts` but not
+  yet exposed; the sidecar is the natural place to add them.

+  Connects to iMessage (and other Spectrum interfaces) through Photon's
+  managed Spectrum platform. Both directions run over the `spectrum-ts`
+  SDK's long-lived gRPC stream via a small supervised Node sidecar —
+  inbound messages arrive on the SDK's `app.messages` stream (no webhook,

+
+  The plugin ships with a `hermes photon` CLI for the one-time device
+  login + project + user setup. Runtime credentials are written to
+  ``~/.hermes/.env`` (``PHOTON_PROJECT_ID`` = the Spectrum project id,
+  ``PHOTON_PROJECT_SECRET``) like every other channel, with management
+  metadata (device token, dashboard project id) in ``~/.hermes/auth.json``.
+  Photon's free shared-line model lets users get started without a paid plan.

+# Photon sidecar
+
+Small Node helper that bridges Hermes Agent to Photon's Spectrum SDK
+(`spectrum-ts`).  Hermes is Python; Photon has no public HTTP
+send-message endpoint today; replies therefore go through this sidecar.
+
+The sidecar:
+
+- runs `Spectrum({ projectId, projectSecret, providers: [imessage.config()] })`
+- exposes a loopback-only HTTP control channel for the Python adapter
+  to push send/typing requests (auth via `X-Hermes-Sidecar-Token`)
+- drains the inbound message stream so `spectrum-ts` keeps its
+  reconnect/heartbeat machinery alive (real inbound delivery is via
+  Photon's signed webhook hitting our Python aiohttp server)
+
+## Install
+
+```bash
+cd plugins/platforms/photon/sidecar
+npm install
+```
+
+The Hermes plugin's `hermes photon setup` command runs `npm install`
+here automatically.
+
+## Run standalone
+
+For debugging:
+
+```bash
+PHOTON_PROJECT_ID=... PHOTON_PROJECT_SECRET=... \
+PHOTON_SIDECAR_PORT=8789 PHOTON_SIDECAR_TOKEN=$(openssl rand -hex 16) \
+node index.mjs
+```
+
+In normal use, the Python adapter supervises this process — start,
+restart on crash, kill on shutdown — and never asks the user to run
+it by hand.
+
+## Why a sidecar at all?
+
+Photon publishes webhooks (inbound) but their docs state explicitly:
+
+> Pass `space.id` to `Space.send(...)` from a separate `spectrum-ts`
+> SDK instance to reply.  No public HTTP send endpoint exists today.
+
+— https://photon.codes/docs/webhooks/events
+
+When Photon ships an HTTP send endpoint, the plan is to retire this
+sidecar entirely and call it directly from Python.  The plugin's
+outbound code path is already isolated behind a single helper
+(`_sidecar_send` in `adapter.py`) to make that swap a one-file change.

+// Hermes Agent — Photon Spectrum sidecar
+//
+// Spawned by `plugins/platforms/photon/adapter.py` to bridge BOTH directions
+// of messaging to Photon's Spectrum platform via the `spectrum-ts` SDK (the
+// SDK is TypeScript-only, so a Node sidecar is unavoidable — there is no
+// Python SDK and no public HTTP message API).
+//
+// Inbound  (gRPC -> Hermes): the SDK's `app.messages` async iterator is a
+//   long-lived gRPC stream. We serialize each `[space, message]` to a
+//   normalized JSON event and stream it to the Python adapter over a
+//   loopback `GET /inbound` (NDJSON). We pause pulling from the stream while
+//   no consumer is attached so a backlog isn't pulled-and-lost before the
+//   gateway connects.
+// Outbound (Hermes -> gRPC): `/send` drives `space.send(...)`; `/typing`
+//   sends the documented `typing("start" | "stop")` content builder.
+//
+// Protocol (all requests require `X-Hermes-Sidecar-Token: ${TOKEN}`):
+//   - GET  /inbound    -> 200 NDJSON stream; one JSON event per line, blank
+//                         lines are heartbeats. One consumer at a time.

+//       body: {"spaceId": "...", "text": "..."}
