refactor: optimize CLAUDE.md context footprint (-49%)

Extract Ollama docs and PROJECT_STATE locking protocol to on-demand
reference files. Trim Work Mode to detection table only. Remove verbose
anti-pattern examples and credential encryption details.

+# PROJECT_STATE.md Locking Protocol
+
+This protocol prevents conflicts between concurrent Claude sessions. Follow it for every significant action on any project that has a PROJECT_STATE.md.
+
+## What Requires a Lock
+
+- Editing or creating source code files
+- Git commit or push
+- SSH command that modifies a server (deploy, install, config change, service restart)
+- Database schema change or data migration
+- Build pipeline modification
+
+Reading files, planning, and answering questions do NOT require a lock.
+
+## The Protocol
+
+**Step 1 — Read before acting**
+Re-read PROJECT_STATE.md before starting:
+- Check Active Session Locks: is anything locked that you need to touch?
+- Conflicting lock < 2 hours old: stop, report to user, ask how to proceed.
+- Lock > 2 hours old (stale): note it to user, clear the row, proceed.
+
+**Step 2 — Claim your lock**
+Add a row to Active Session Locks before performing the action:
+
+| Session | Working On | Status | Blocks | Started |
+|---------|-----------|--------|--------|---------|
+| DESKTOP-0O8A1RL/Claude | Brief description | IN_PROGRESS | What others must avoid | HH:MM UTC |
+
+Use `{machine}/{Claude or agent description}` as the Session identifier.
+
+**Step 3 — Perform the action**
+
+**Step 4 — Update on completion OR failure**
+1. Remove your lock row
+2. Add a Recent Changes entry with status: `COMPLETE`, `FAILED`, `PARTIAL`, or `ROLLED_BACK`
+3. Update Current Project State if any component status changed
+4. Check off completed Pending items
+
+## Stale Lock Rule
+
+A lock older than 2 hours with no timestamp update is abandoned. Clear it, note `[Cleared stale lock from {session}]` in Recent Changes, then proceed.
