"""Scribe-plugin support endpoints.

Consumed by the Scribe Claude Code plugin (not the web UI). `GET /api/plugin/
context` is curled by the plugin's SessionStart hook to push the operator's
always-on rules + active-project context into the session — Scribe's own push
channel. Auth is the standard `@login_required` path, which accepts a `Bearer
fmcp_<key>` API key (a read-scoped key suffices for this GET).
