chore(release): finalize v3.8.13 changelog and cleanup

Finalize the v3.8.13 changelog with release date, maintenance notes,
and contributor credits. Update MCP docs to reference the correct tool
inventory diagram, exclude nested .claude worktrees from ESLint scans,
and tighten a response sanitizer type guard.

 - **fix(sse):** expose the Claude (`claude-opus-4-6-thinking`, `claude-sonnet-4-6`) and Gemini budget tiers (`gemini-3.1-pro-{high,low}`, `gemini-3.5-flash-{low,extra-low}`) in the Antigravity catalog — they are user-callable on the Antigravity OAuth backend (agy parity), correcting an earlier assumption that Claude had been removed. ([#3303](https://github.com/diegosouzapw/OmniRoute/pull/3303), discussion #3184 — thanks @diegosouzapw)
 - **fix(catalog):** compute a combo's `context_length` from the known targets only — a single target with unknown context no longer collapses the whole combo to `undefined`; also accepts live `{id, contextLength}` model entries in the opencode-provider helper (follow-up to #3298). ([#3304](https://github.com/diegosouzapw/OmniRoute/pull/3304) — thanks @herjarsa / @diegosouzapw)
 
+### 📝 Maintenance
+
+- **test(catalog):** align the Antigravity preview-alias catalog test with the #3303 budget tiers — asserts the restored Claude/Gemini tiers are surfaced, locking in the behavior so a future tier change can't silently drop them again (thanks @diegosouzapw)
+- **docs:** rename the `resolve-issues` skill references to `review-issues` across the docs/skill surfaces, matching the renamed governance skill (thanks @diegosouzapw)
+- **chore(release):** open the v3.8.13 development cycle (version bump + cycle bookkeeping) and finalize this changelog (thanks @diegosouzapw)
