* fix(#4830): re-land #4768's letter-suffix phase-id fix and its lint-phase-id-drift ratchets on current next
Commit 740ba0d8a (#4781) removed every change #4768 had merged for #4748:
the first-non-digit split at execute-phase.md's two arithmetic sites, the
init-emitted `padded_phase` the REVIEW.md lookup binds instead of
`printf "%02d"`, the canonical-grammar extractions in autonomous.md and
plan-review-convergence.md, the `.changeset/zesty-wolves-tumble.md`
fragment, and the three lint-phase-id-drift ratchets with their tests.
The guard and the code it guarded left together, so nothing went red.
This is a cherry-pick of 092d9256b onto current `next`, resolved against
the #4683 threat-id fields on execute-phase.md's Parse-JSON line, with the
changeset `pr:` reset to the placeholder and the compact-content benchmark
baseline regenerated against the current base.
(cherry picked from commit 092d9256b8)
