feat(cloud-agent): show workspace commits in chat

[eshurakov]

Summary

• Show managed workspace commits as subdued transcript entries with hover/tap metadata details.
• Preserve immutable commit identity, bounded actual messages, turn attribution, replay deduplication, and truthful push status.
• Keep the existing saved worktree viewer; this feature does not add historical commit diffs.

Verification

No manual browser or live-provider tests were rerun during this restack. Existing feature work was restored from a named stash and integrated with the merged parent; the original local handoff and evidence remain excluded.

Visual Changes

Adds compact commit metadata disclosures in the transcript. No screenshots were captured or uploaded during this restack.

Reviewer Notes

Stacked on main as #5816, with #5817 on top. Four commits after rebase onto latest main. The rebase resolution preserves both upstream sibling-serialization cases and the new commit-identity tests.

Targeted lint and web/SDK/shared/service/wrapper typechecks passed. 926 distinct focused tests passed, including auto-commit/events, SDK projection, commit parsing, isolated web presentation, and six Workers-runtime replay/deletion-fencing tests with mocked external boundaries. Web tests omitted database setup and are not E2E evidence.

The additional standalone services/cloud-agent-next/test/tsconfig.json check is not clean: 711 diagnostics include existing mixed-runtime/mock typing and pending-feature fixture typing. The normal package typechecks pass; no broad test-project cleanup is included.
