chore: sync local state

Estate-wide chore-drift sweep committing accumulated local state
(gitignore, lockfiles, dotfile tweaks, workflow SHA bumps, A2ML
migration drift, doc sweeps) so the estate-wide Dependabot fix
propagation can proceed without skipping this repo.

No source-file edits were in scope for this commit; repos with
in-flight source work were excluded and kicked back for manual
review.
