chore(docs,config): slice-3 + #57-closure state note; git-workflow perms (Refs #488)

Wrap-up bookkeeping after the res-to-affine Phase 3 declaration translator
completed (#57 closed; successor #488 filed).

- STATE.a2ml — dated session note for slice 3 (literal let->const, #484), the
  #57 closure, and the #488 successor (partial-port mode + qualified-ref
  resolution); last-updated bumped to 2026-05-31.
- .claude/settings.json — add the git workflow commands (add / commit / rebase
  / checkout / switch / restore / reset / push) to the permission allowlist,
  matching the implement->commit->rebase->push loop the wrap-ups run; existing
  entries + the SessionStart hook are preserved.

Docs/config only, no code touched. settings.json valid JSON; doc-truthing
guard passes; STATE.a2ml mirror keys intact.
