feat(acp-registry): switch to uvx distribution, drop npm launcher

The ACP Registry schema supports uvx as a first-class distribution method
alongside npx and binary. Pointing the registry directly at the existing
hermes-agent PyPI release removes:

- the @nousresearch npm scope (we don't own it)
- a separate npm publish step on every weekly release
- 90 lines of Node launcher + tests in packages/hermes-agent-acp/

The Zed registry now installs Hermes via:

  uvx --from 'hermes-agent[acp]==<version>' hermes-acp

This is the same command the npm launcher was shelling out to anyway, so
end-user behavior is unchanged. Registry CI validates the PyPI URL +
version-pin exact match automatically.

Changes:
- acp_registry/agent.json: distribution.npx -> distribution.uvx
- delete packages/hermes-agent-acp/ entirely
- scripts/release.py: drop npm-launcher bump paths, keep manifest lockstep
- tests/acp/test_registry_manifest.py: assert uvx shape + version pin
- tests/scripts/test_release_acp_registry.py: rewrite for uvx-only shape
- docs (user-guide + dev-guide): drop all npm-launcher references
- delete docs/plans/acp-registry-zed-integration.md (stale, npm-shaped)

Validated against agentclientprotocol/registry agent.schema.json via
jsonschema. hermes-agent==0.13.0 is already live on PyPI.

-# Hermes Agent ACP Registry + Zed Integration Implementation Plan
-
-> For Hermes: Use subagent-driven-development skill to implement this plan task-by-task.
-
-Goal: Make Hermes Agent installable from Zed's official ACP Registry, so users can add Hermes from Zed's agent panel without manual custom `agent_servers` settings.
-
-Architecture: Use the official `agentclientprotocol/registry` flow instead of the deprecated Zed Agent Server Extension path. Ship a registry-compatible launcher distribution, advertise valid ACP auth methods during every handshake, validate against official registry schema and auth CI, then submit a registry PR for `hermes-agent`.
-
-Tech Stack: Hermes Agent Python package, ACP adapter (`hermes acp` / `hermes-acp`), npm launcher package, official ACP Registry JSON schema, Zed external agent UI.
-
----
-
-## Compliance constraints
-
-- Zed v0.221.x+ prefers the ACP Registry for external agents; do not use Zed Agent Server Extensions for distribution.
-- Registry repo layout is top-level `hermes-agent/agent.json` and `hermes-agent/icon.svg`, not `agents/hermes-agent/`.
-- Registry metadata must use the official schema: `id`, `name`, `version`, `description`, `distribution`, optional `repository`, `website`, `authors`, `license`.
-- Distribution must be exactly one supported type unless intentionally adding another: `binary`, `npx`, or `uvx`.
-- Hermes must advertise at least one valid `authMethods` entry on a clean first-run handshake. No-provider/no-auth is not compliant.
-- Terminal Auth must be explicit and deterministic: `id: hermes-setup`, `type: terminal`, `args: ["--setup"]`.
-- `icon.svg` must be 16x16, square, monochrome, and use only `currentColor` / `none` for fill/stroke; no gradients, hardcoded colors, or `url(#...)` paints.
-- ACP server mode must reserve stdout for JSON-RPC only. Diagnostics/logs go to stderr. `--version`, `--check`, and `--setup` are not server mode and may print normally.
-- Published npm package must exist and be runnable before the upstream registry PR references it.
-
----
-
-## Tasks
-
-1. Verify/implement ACP auth methods.
-   - Always return terminal setup auth from `initialize()`.
-   - Return configured provider auth in addition when provider credentials are resolvable.
-   - Add tests for provider auth, terminal fallback auth, and authenticate behavior before/after provider setup.
-
-2. Add non-interactive ACP commands.
-   - `hermes acp --version`
-   - `hermes acp --check`
-   - `hermes acp --setup`
-   - Same behavior through `hermes-acp`.
-
-3. Build npm launcher package.
-   - Package: `@nousresearch/hermes-agent-acp@<version>`.
-   - Command: `uvx --from 'hermes-agent[acp]==<version>' hermes-acp ...args`.
-   - Fallback: `uv tool run --from ...` when only `uv` exists.
-   - Forward all args, including `--setup`, `--version`, and `--check`.
-   - Preserve stdio in server mode.
-   - Print actionable stderr error when `uv`/`uvx` is missing.
-
-4. Replace local registry metadata.
-   - Convert `acp_registry/agent.json` from old command-style local format to official registry schema.
-   - Replace `acp_registry/icon.svg` with compliant 16x16 currentColor icon.
-   - Add tests rejecting old fields (`schema_version`, `display_name`, `distribution.type`, `distribution.command`) and unknown distribution keys.
-
-5. Update docs.
-   - Zed docs show official ACP Registry install first: Add Agent / `zed: acp registry` -> search Hermes Agent -> install.
-   - Manual `agent_servers` JSON remains only as local-development fallback.
-   - Docs include `uv` prerequisite and `hermes acp --check` troubleshooting.
-   - Developer internals mention npm launcher and terminal setup auth.
-
-6. Validate locally.
-   - `python -m pytest tests/acp/test_auth.py tests/acp/test_server.py tests/acp/test_entry.py tests/acp/test_registry_manifest.py -q`
-   - `(cd packages/hermes-agent-acp && npm test)`
-   - `(cd packages/hermes-agent-acp && npm pack --dry-run)`
-   - `hermes acp --version`
-   - `hermes acp --check`
-
-7. Validate against official registry tooling before PR.
-   - In a clone/fork of `agentclientprotocol/registry`, copy files into top-level `hermes-agent/`.
-   - Run official dry-run build, e.g. `uv run --with jsonschema .github/workflows/build_registry.py --dry-run`.
-   - Run official auth check if available, e.g. `.github/workflows/scripts/run-registry-docker.sh python3 .github/workflows/verify_agents.py --auth-check`.
-   - Fix any schema/auth issues before submitting.
-
-8. Publish and submit.
-   - Publish `@nousresearch/hermes-agent-acp@<version>`.
-   - Verify published package:
-     - `npx @nousresearch/hermes-agent-acp@<version> --version`
-     - `npx @nousresearch/hermes-agent-acp@<version> --check`
-     - ACP initialize/authMethods smoke test through the published package.
-   - Open PR to `agentclientprotocol/registry` adding `hermes-agent/agent.json` and `hermes-agent/icon.svg`.
-
-9. End-to-end Zed verification.
-   - Install Hermes Agent through Zed's ACP Registry.
-   - Start a Hermes thread.
-   - Verify workspace cwd, file tools, terminal tools, tool rendering, and approval prompts.
-
----
-
-## Acceptance criteria
-
-- Hermes appears in Zed's official ACP Registry UI.
-- Install starts Hermes without custom Zed settings.
-- Registry CI passes schema and auth validation.
-- ACP stdout remains JSON-RPC only; all logs go to stderr.
-- `authMethods` are present and valid on clean first run.
-- Terminal Auth can launch Hermes provider/model setup with `--setup`.
-- Zed workspace cwd is honored by Hermes file and terminal tools.
-- Docs describe registry install first and manual custom config second.
-- Package/release automation prevents registry entries from pointing at unpublished versions.

-ACP launcher for Hermes Agent.
-
-This package is intended for clients such as Zed that install agents through the official ACP Registry. It launches the Python Hermes ACP server with:
-
-```bash
-uvx --from 'hermes-agent[acp]==0.13.0' hermes-acp
-```
-
-## Requirements
-
-- Node.js 18+
-- `uv` or `uvx` on PATH
-- Hermes provider credentials configured with `hermes model`, or through Hermes' normal `~/.hermes/.env` / `~/.hermes/config.yaml` setup
-
-## Commands
-
-```bash
-npx @nousresearch/hermes-agent-acp@0.13.0 --version
-npx @nousresearch/hermes-agent-acp@0.13.0 --check
-npx @nousresearch/hermes-agent-acp@0.13.0 --setup
-npx @nousresearch/hermes-agent-acp@0.13.0
-```
-
-Normal no-argument mode reserves stdout for ACP JSON-RPC traffic. Diagnostics are emitted on stderr by Hermes.
