Refine AI hook pipeline and tighten gh permissions

- session-start.sh: use session_id from hook input instead of
  generating a custom one, with fallback to timestamp-pid
- post-edit-record.sh, stop-format.sh: use ${TMPDIR:-/tmp} instead
  of hardcoded /tmp to respect contributor's environment
- stop-format.sh: skip formatting and tests entirely when no files
  were edited this turn (no wasted Docker containers on read-only turns)
- settings.json: replace broad Bash(gh pr:*) and Bash(gh api:*) with
  granular read-only allows (view, list, diff, checks, status, search);
  write operations (create, edit, comment, merge) prompt by default
