Introduce tools/quick_gate.py: a one-second check that parses every file
in protocol, tests and tools, imports each protocol module, and runs the
functional tests of the labs that need no experiment data.
Wire it to a PostToolUse hook so edits under protocol or tests are checked
automatically, and add two read-only review agents with slash commands that
drive them: verifier for independent re-derivation of results, adversary for
unsafe-state hunting in control, failsafe, session and reset code.
