Make Photon iMessage a first-class persistent-connection channel like
Discord/Slack, using the spectrum-ts gRPC stream for both directions.
- Inbound: the sidecar forwards the SDK's app.messages gRPC stream to the
adapter over a loopback GET /inbound (NDJSON) instead of webhooks. Drops
the aiohttp webhook server, HMAC signature verification, public URL, and
PHOTON_WEBHOOK_* config; adapter reconnects with backoff.
- Management plane: device login uses client_id=photon-cli against the
single dashboard host (Bearer), matching the official photon-hq/cli;
find-or-create "Hermes Agent" project, enable Spectrum, rotate secret,
register user (with phone dedup), surface the assigned iMessage line.
- SDK projectId is the project's spectrumProjectId, not the dashboard id;
runtime creds persist to ~/.hermes/.env like every other channel.
- CLI: 6-step setup, webhook subcommands removed.
- Tests/docs updated for the gRPC flow; sidecar pins spectrum-ts ^1.17.1.
