ClaudeTools cleanup: drop dead context-recall layer, unify /save + /sync

Deletions (~1,500 lines of dead docs):
- .claude/hooks/ — docs-only directory, no executables. Referenced scripts
  setup-context-recall.sh / test-context-recall.sh did not exist. Hooks
  would have POSTed to localhost:8000; the API actually ran at
  172.16.3.30:8001 and is no longer in use.
- .claude/AUTO_CONTEXT_SYSTEM.md — 347-line duplicate spec of CLAUDE.md's
  Automatic Context Loading section, referencing unimplemented hooks.
- .claude/URGENT-vault-path-bug.md — 217-line urgency note for a fix that
  already shipped weeks ago.
- .claude/context-recall-config.env.example — config template for the same
  dead system.

Refactors (~500 lines net removed):
- /save and /sync now wrap bash .claude/scripts/sync.sh as the single
  source of truth for git ops. /save adds a session-log-writing step in
  front; /sync invokes the script directly.
- Dropped /sync's manual git phases that contradicted sync.sh.
- Dropped the cp -r ~/ClaudeTools/.claude/commands/* ~/.claude/commands/
  step (clobbered per-user customization in the multi-user model).
- Dropped auto-invoke of /refresh-directives (command does not exist).
- Dropped references to directives.md (file does not exist).
- /save now documents the rm -f save_narrative_prompt.txt step, fixing
  the stale-prompt bug Howard documented in feedback_tmp_path_windows.md.

Fixes:
- CLAUDE.md SESSION_STATE.md reference replaced with the canonical
  PROJECT_STATE.md (per-project, with protocol at
  .claude/PROJECT_STATE_PROTOCOL.md). 16 client folders already use
  PROJECT_STATE.md; SESSION_STATE.md was only a stale reference.

 ## Context Recovery
 
 When user references previous work, use `/context` command. Never ask for info in:
-- `credentials.md` — Infrastructure reference (being migrated to SOPS vault at D:\vault)
+- `credentials.md` — Infrastructure reference (being migrated to SOPS vault)
 - `session-logs/` — Daily work logs (also in `projects/*/session-logs/` and `clients/*/session-logs/`)
-- `SESSION_STATE.md` — Project history
+- `projects/*/PROJECT_STATE.md` and `clients/*/PROJECT_STATE.md` — per-project state (active locks, current state, recent changes). Loaded automatically per Trigger 2 above; protocol at `.claude/PROJECT_STATE_PROTOCOL.md`
