Add devops.git.assert_branch so agents can fail fast before mutating git commands when concurrent sessions drift HEAD. Update agent skills with worktree isolation guidance and resolve the shared-worktree branch race issue. Co-authored-by: Alex Vardakostas <Al-does@users.noreply.github.com>

What changed
devops.git.assert_branchhelper and CLI to fail fast when HEAD drifted before mutating git operations.record-agent-issueandvast-provisioningskills.resolved/with updated resolution history.Tradeoffs
Cursor platform behavior is unchanged; this adds a lightweight guard agents can call before writes. Separate worktrees per concurrent agent remains the strongest isolation.
Verification
uv run pytest -q tests/test_git_assert_branch.py -m "not slow"Reviewer notes
Confirm skill guidance is sufficient for agents importing results or pushing from shared Mac worktrees. The helper is intentionally small and does not wrap git itself.
