feat(t27b): doctor decides in steward.t27 and sees a stuck checkout

[gHashTag]

Closes #6230
Refs #6198, #6063

Fourth slice of the owner rule "t27b and its tooling are written in t27".

• specs/tri/t27b/steward.t27: lab_stale, claim_code, railway_old, ledger_quiet, checkout_code + 12 tests (50 total).
• t27b.py doctor passes minutes and words the finding; no threshold branch of its own (checked by the test).
• Fixes found on the live lab (18:20Z): a stuck lab (failed checkout, no finished) never went LAB-STALE; the checkout failure was a generic LAB-TESTS-RED. Now LAB-STALE from updated, LAB-CHECKOUT with error + fix, LAB-RECLONED for fix(t27b-lab): a clone that cannot check out is cloned again #6220's heal.

Evidence

• t27c test-report on the t27c lab (master binary): 50/50, invariant comptime.
• t27b test --check: 50 passed, 66 runtime asserts, invariant held.
• gen/c/tri/t27b/steward.c = lab gen-c output, sha256 4cb7330b..., 13164 bytes, fetched byte for byte.
• test_a_t27b_tick_reads_before_it_acts.py: 45 ok, new stuck / healed / kept fixtures; mutation control (gen C checkout rule disabled) loses LAB-CHECKOUT.
• test_the_t27b_steward_decides_in_t27.py and test_a_t27b_spec_cannot_move_silently.py: PASS.
• Live doctor on the current lab: LAB-CHECKOUT commit bae81aee2: ... promisor remote (was LAB-TESTS-RED checkout).

Expected red: the L2 step of L1 TRACEABILITY flags the regenerated gen/ file (#6226); it does not run on master.
