feat(queen): give the bees t27c and let the review measure the commit

The review ran on the bee's own VERDICT block. Measured 2026-09-10
(gHashTag/t27#3560): of 34 finished branches, 20 did not parse, 4 parsed
with DISCARDED tokens, 1 regressed typecheck. Neither bee nor reviewer had
the compiler.

• Dockerfile: standalone t27c stage (rust:1-bookworm, sparse clone of
  bootstrap+gen, root Cargo.lock, no --locked), binary at
  /usr/local/bin/t27c, built ref at /usr/local/share/t27c/REF.
• queen-dispatch: witnessSpecs() reads each changed .t27 from the COMMIT
  (git show queen-N:file) and runs parse / parse-complete / typecheck as
  the bee; typecheck is a ratchet against TRIOS_REPO_REF, not a gate.
• queen-tick: machine verdicts join the bee's; unmet ones count against
  the send-back ceiling. Specs changed but no t27c => escalate, never
  accept. The brief names t27c and dictates the 'Closes #N' trailer the
  t27 L1 gate accepts.
• tests: queen-witness.test.ts (20 pass, 2 gated on queend).

Evidence

• bun test tests/api/queen-witness.test.ts: 20 pass (2 gated on a running queend).
• Dockerfile builds t27c from gHashTag/t27 in a stage and copies the binary to /usr/local/bin/t27c.

Round 5 of the Queen tabs work (t27#3560 harvest). The scheduler PR is stacked on this branch.
