ci(plugin): gate plugin/** — the path that shipped two live defects
`plugin/` is not built into the image; installs fetch it from this repo via
.claude-plugin/marketplace.json, so a push IS the release. It was absent
from the workflow's `paths:` filter entirely, meaning plugin changes ran no
CI at all. Two separate defects reached a live install through that gap:

  #2198 — all four hook scripts inert (lowercase userConfig env vars,
          line-oriented `jq -rR`, line-oriented `cut -c`)
  #2209 — the fix for #2198 couldn't reach an install because the manifest
          version wasn't bumped, so the installer never refreshed its cache

Adds `plugin/**` + `.claude-plugin/**` to `paths:` and a `plugin` job
running scripts/check_plugin.py:

1. `bash -n` on every hook.
2. The three known-bad patterns from #2198. Verified by replay against
   c569cdd^ — all three are caught. Narrow by design; see below.
3. Shipped plugin content differs from origin/main => the manifest version
   must differ too. Stated against the base branch, not per-commit, so a
   batch needs one bump rather than one per commit. Replayed against
   c569cdd: correctly fails.

The checker found a real outstanding bug on its first run: the `cut -c1-2000`
prompt cap in scribe_autoinject.sh was still line-oriented. Only the
prior-art hook's copy got fixed in c569cdd. Now `head -c`. It then failed
on this very commit for a missing version bump, which is the third time
that rule has mattered and the first time something other than memory
enforced it. Manifest bumped to 0.1.20.

WHAT THIS DOESN'T COVER, and why. shellcheck is the right tool for check 2
and is NOT in ci-python; nor is jq, which every hook requires and silently
bails without — so a "runs and stays silent" smoke test would pass
vacuously today and prove nothing. Both need those two packages added to
the CI image in the CI-runner repo, which is a separate change to a
separate repo (rule #5: the toolchain comes from the image, not from
apt-get at job start). Verified against CI-runner's Dockerfile and
scripts/install-common.sh rather than assumed (rule #37).

`plugin` is not in the build job's `needs`: the plugin doesn't ship in the
image, and blocking the build wouldn't un-publish a bad hook — the push
already did. A failed job still reddens the run.

Closes #2204

# Scribe plugin — UserPromptSubmit push channel (knowledge auto-inject, Path A).
#
# On each user prompt, asks the operator's Scribe instance for a TITLE-FIRST
# awareness hint: the few notes that clear the per-user auto-inject gates
# (high-confidence threshold, margin gate, session dedup, top-k). Titles + ids
# only — never bodies; the agent calls get_note(id) to pull anything it judges
# relevant. Most turns inject nothing.
#
# Best-effort enrichment ONLY: unlike the SessionStart channel there is no
# static floor here. If the instance is unconfigured/unreachable, or anything
# fails, the hook stays SILENT and exits 0 — it must never block a prompt.
#
# Config (same as scribe_session_context.sh), exported to the hook by Claude Code
# with the userConfig key UPPERCASED (see #2198 — reading the lowercase spelling
# silently disables this hook, and silence is indistinguishable from "nothing
# cleared the threshold"):
# CLAUDE_PLUGIN_OPTION_API_ENDPOINT base URL, no trailing slash
# CLAUDE_PLUGIN_OPTION_API_TOKEN fmcp_ API key (sensitive)
# SCRIBE_URL / SCRIBE_TOKEN override for the settings.json dogfooding path.
#
# Session dedup: each surfaced note id is remembered in a per-session file so a
# note is injected at most once per session. Passed back as exclude_ids.
