docs(map): document v0.18.0 symbols + backfill migrations 060/061

Adds fable-mode, X feature-spotlight, and design-bar symbols across the map
slices (+ _complete_map mirror); backfills migrations 060 (drop_messaging) and
061 (x_feature_spotlight), both previously undocumented; corrects the ORM table
count 37->38; adds the _briefing_for include_company_goals row.

 > Post-snapshot updates (since 2026-06-29): commit 536bbb64 ("Chore/all/logical gaps sweep #286") touched content_actions.py and rate_limit_tracker.py in this slice. (1) rate_limit_tracker: activate() is now a Lua atomic merge (_ACTIVATE_RATE_LIMIT) that carries over the previous probe_failures count — the increment-vs-activate race is closed. (2) content_actions: _curate_playbook wraps the gating session.commit() in try/except PendingRollbackError; a poisoned session now returns a clean Envelope.invalid_state instead of 500-ing, and an uncommitted playbook cannot fall through to the RAG index.

+> **v0.18.0** (2026-07-04): X feature-spotlight adds `ContentActions.propose_feature_spotlight` (content_actions.py:1238) + `_FEATURE_SPOTLIGHT_ROLES = frozenset({"head_marketing"})` (line 313), mirroring `pitch`'s Board-gated-verb shape. **Gap found (static read, not live-verified):** this verb has no wrapper function or `_TOOLS` entry in `roboco/mcp/do_server.py` (unlike `propose_roadmap`, which has both), so `_register_tools()`'s manifest∩`_TOOLS` intersection never exposes it to a spawned Head-of-Marketing agent despite the role-config grant — see mcp-servers.md Regression Risks.
