feat(reviewer-preflight): check Workspace mutations handoff fields

- Updated mcp_server.py operator guide entries to use jenkins-mcp / glitchtip-mcp names matching mcp-control-plane.
- Added reload/reconnect instructions for clients in notes.
- Added test for 'enabled but no usable tools' negative assertion.
- Updated EXPECTED_SKILLS and assertions in test_operator_guide.py.

Scoped to issue #146. Author profile.

+"""Fail-closed branch-identity proofs for author workflows (#177).
+
+Author-side counterpart of the reviewer proofs in ``review_proofs.py``
+(#173). During the #173 implementation itself, a commit landed on local
+``master`` because the shared checkout's branch moved mid-session (origin
+incident of #177). These helpers turn that from an after-the-fact repair
+into a fail-closed gate: an author workflow must prove its local git state
+before staging, committing, or pushing.
+
+The helpers are pure (no git calls): the workflow gathers the raw facts
+(``git branch --show-current``, ``git rev-parse HEAD``, the push refspec,
+the branch named in the issue claim) and passes them in, so the same logic
+works from prompts, harness assertions, and tests. Shared-worktree branch
+switches by other sessions are treated as expected events to detect, not
+exceptional ones. Nothing here weakens the review/merge/permission gates.
