Phase 1 of plan #755 (Scribe-as-plugin). Gives Scribe its own session-start
push channel so always-on rules + active-project context surface without being
asked — the gap behind 'I have to prompt for everything'.
- services/plugin_context.build_session_context: renders always-on rule titles
grouped by topic (under the 10k additionalContext cap; full text stays one
list_always_on_rules/get_rule call away) + optional project goal/open-task
count + a recall/update-over-create reflex line. Capped at 9000 chars.
- routes/plugin GET /api/plugin/context (login_required already accepts Bearer
fmcp_ keys; read scope suffices).
- tests: titles-not-statements, project scoping, length cap (pure mocks).
- scripts/scribe_session_context.sh: dogfood SessionStart hook, fail-open,
reads url+token from .mcp.json. Superseded in Phase 2 by the plugin-bundled
hook using userConfig.
