Tom Boucher 9d55d531a4 fix(#2432,#2424): pre-dispatch PLAN.md commit + reapply-patches baseline detection; docs(#2397): config schema drift (#2469)
- quick.md Step 5.6: commit PLAN.md to base branch before worktree executor
  spawn when USE_WORKTREES is active, preventing CC #36182 path-resolution
  drift that caused silent writes to main repo instead of worktree
- reapply-patches.md Option A: replace first-add commit heuristic with
  pristine_hashes SHA-256 matching from backup-meta.json so baseline detection
  works correctly on multi-cycle repos; first-add fallback kept for older
  installers without pristine_hashes
- CONFIGURATION.md: move security_enforcement/security_asvs_level/security_block_on
  to workflow.* (matches templates/config.json and workflow readers); rename
  context_profile → context (matches VALID_CONFIG_KEYS in config.cjs); add
  planning.sub_repos to schema example
- universal-anti-patterns.md + context-budget.md: fix context_window_tokens →
  context_window (the actual key name in config.cjs)

/**
* Bug #2424: reapply-patches pristine-baseline detection uses first-add commit
*
* The three-way merge baseline detection previously used `git log --diff-filter=A`
* which returns the commit that FIRST added the file. On repos that have been
* through multiple GSD update cycles, this returns a stale, many-versions-old
* baseline — not the version immediately prior to the current update.
*
* Fix: Option A must prefer `pristine_hashes` from backup-meta.json to locate
* the correct baseline commit by SHA-256 matching, with a fallback to the
* first-add heuristic only when no pristine hash is recorded.
