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: Audit
+
+## Intent Classification
+
+**Triggers:** Security reviews, inventory checks, compliance, "what's the state of..."
+
+## Fixed Output Format
+
+```markdownn## Scope
+[What was audited]
+
+## Findings
+| Item | Status | Notes |
+|------|--------|-------|
+| [item1] | ✅/⚠️/❌ | [notes] |
+| [item2] | ✅/⚠️/❌ | [notes] |
+
+## Risks Identified
+- [Risk 1]
+- [Risk 2]
+
+## Recommendations
+- [Rec 1]
+- [Rec 2]
+
+## Verification
+[How findings were confirmed]
+```
+
+## Tool Access Rules
+
+1. **Enumerate** - list everything in scope
+2. **Inspect** - check state of each item
+3. **Assess** - evaluate against standards
+4. **Report** - structured findings with evidence
+
+## Constraints
+
+- NO: Assumptions without verification
+- NO: Partial coverage reported as complete
+- NO: Risks without severity assessment
+- YES: Evidence cited for each finding
+- YES: Actionable recommendations

+# Workflow: Coding
+
+## Intent Classification
+
+**Triggers:** Code changes, development tasks, bug fixes, feature implementation
+
+## Fixed Output Format
+
+```markdown
+## Summary
+[What changed - 1-2 sentences]
+
+## Files Modified
+| File | Change |
+|------|--------|
+| file1.py | [description] |
+| file2.js | [description] |
+
+## Verification
+- [ ] Tests pass: `command`
+- [ ] Lint passes: `command`
+- [ ] Manual verification: [how]
+
+## Decisions Made
+- [Decision 1]
+- [Decision 2]
+
+## Still Open
+- [ ] [if any]
+```
+
+## Tool Access Rules
+
+1. **Delegate to coding agents** when possible
+2. **Read before writing** - always check existing code first
+3. **Verify before reporting** - tests, lint, manual check
+4. **Update memory** - log decisions to DECISIONS.md
+
+## Constraints
+
+- NO: Direct production edits without verification
+- NO: Untested code reported as "done"
+- NO: Breaking changes without migration plan
+- YES: Clear acceptance criteria before starting
+- YES: Root cause analysis before fixes

+# Workflow: Troubleshooting
+
+## Intent Classification
+
+**Triggers:** Errors, failures, unexpected behavior, debugging requests
+
+## Fixed Output Format
+
+```markdown
+## Problem
+[Symptom observed]
+
+## Diagnosis
+- Checked: [what was checked]
+- Found: [what was found]
+
+## Cause
+[Root cause - trace to why, not just what]
+
+## Fix
+[What was changed]
+
+## Validation
+[How verified it's fixed]
+```
+
+## Tool Access Rules
+
+1. **Inspect first** - logs, config, state before changing anything
+2. **Reproduce** - understand the failure before fixing
+3. **Trace to root** - fix cause, not symptom
+4. **Document** - add to ISSUES.md if pattern
+
+## Constraints
+
+- NO: Restart-as-first-response
+- NO: Regex patches without understanding root cause
+- NO: Fixes without verification
+- YES: Documented workaround if root cause blocked
+- YES: Regression test if applicable

+# 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
