claude-ceo-assistant 62629eda4a ci(canary): rewrite Probe 3 to actually validate auth (NOP push --dry-run)
While verifying Phase 4, found a real flaw in Probe 3 (`git ls-remote
refs/heads/staging`). On a public repo (which molecule-core is), Gitea
falls back to anonymous read on bad auth, so `ls-remote` succeeds even
with a junk token. The probe was therefore green-lighting rotated
tokens — false-green, the worst possible canary failure mode.

Rewritten to use `git push --dry-run` of the current staging SHA back
to `refs/heads/staging`:

- Push always authenticates (auth-gated on smart-protocol handshake,
  before the dry-run can compute the empty-diff).
- NOP by construction: pushing the current tip back to itself is
  "Everything up-to-date" with exit 0.
- Bad token → "Authentication failed", exit 128.
- Doesn't reach pre-receive (where branch-protection authz runs), so
  scope is "auth only" — matches the design intent (failure mode B);
  authz already covered daily by branch-protection-drift.yml.

Implementation note: `git push` requires a local repo. Spinning up a
fresh `git init` in a tempdir (~1KB, ~50ms) instead of pulling the
full repo via actions/checkout — actions/checkout would clone
~hundreds of MB for what amounts to "a place to run git from."

Local mutation tests pass:
- Real token: "Everything up-to-date" exit 0
- Junk token: "Authentication failed" exit 128 with actionable
  ::error:: messages pointing at the runbook
