Merge remote-tracking branch 'origin/main' into garrytan/workspace-aware-ship

Rebumped v1.8.0.0 -> v1.11.0.0 (minor-past main's v1.10.1.0) using
bin/gstack-next-version — the same queue-aware path this branch introduces.
CHANGELOG repositioned so v1.11.0.0 sits above main's new entries
(v1.10.1.0 / v1.10.0.0 / v1.9.0.0).

Conflicts resolved:
- VERSION, package.json: rebumped to v1.11.0.0 (util-picked)
- bin/gstack-config: merged both lists (workspace_root + gbrain keys)
- CHANGELOG.md: hoisted v1.11.0.0 entry above main's new entries

Pre-existing failures in main (4) documented but not fixed in this PR:
1. gstack-brain-sync secret scan > blocks bearer-json (brain-sync tests)
2. no files larger than 2MB (security-bench fixture, already TODO'd)
3. selectTests > skill-specific change (touchfiles scoping)
4. Opus 4.7 overlay pacing directive (expectation stale after v1.10.1.0
   removed the Fan out nudge)
