chore(quality): file-size rebaseline for merge-train 8 (owner-approved, 2026-09-18)

28 ceilings raised to the sizes measured on the combined train tip 04cf8095
(32 contributor PRs boarding release/v3.8.51, all merge-ready; the release tip
itself was green on check:file-size before boarding). Each PR adds a few
irreducible call-site lines to a god-file the ratchet already freezes; the
per-file attribution and the policy reference live in the baseline entry
_rebaseline_2026_09_18_merge_train_8_frozen_growth. Precedent:
_rebaseline_2026_07_23_v3849_merge_train_15.
