Implement consistency architecture (10-principle framework)

Adds:
- ARCHITECTURE.md: Full documentation of 3-layer system
- Context Pipeline: Preprocessing layer (pipeline.js)
- Workflow Router: 4 fixed workflows (coding, debug, deploy, audit)
- Validation Layer: Post-response quality gate (validator.js)
- Format Templates: Structured output templates
- TOOLS.md: Beavault connection documentation

Architecture:
- Layer 1: Behavior rules (always injected)
- Layer 2: Persistent facts (structured memory)
- Layer 3: Ephemeral context
- Priority enforcement: Rules > Prefs > Task > Chat
- Memory write policy: Only confirmed fixes, repeated preferences

+# Workflow: Deployment
+
+## Intent Classification
+
+**Triggers:** Deploy to staging/production, release, infrastructure changes
+
+## Fixed Output Format
+
+```markdown
+## Deployment Summary
+[What and where]
+
+## Pre-Deployment
+- [x] Backup created
+- [x] Tests pass
+- [x] Rollback plan documented
+
+## Changes Applied
+| Step | Command | Status |
+|------|---------|--------|
+| 1 | [command] | ✅ |
+| 2 | [command] | ✅ |
+
+## Verification
+- [x] Service responding: [url]
+- [x] Logs normal: [check]
+- [x] Smoke test: [result]
+
+## Rollback (if needed)
+[Exact rollback steps]
+```
+
+## Tool Access Rules
+
+1. **Check first** - current state before changing
+2. **Backup** - always before production changes
+3. **Verify** - process running, endpoint responding, output correct
+4. **Document** - update RUNBOOK.md if procedure changed
+
+## Constraints
+
+- NO: Deployment without verification plan
+- NO: "It should work" = done
+- NO: Blurry rollback steps
+- YES: Status checked and reported
+- YES: Rollback tested if possible
