docs(tasks): Add Task #101 - Project Instructions Health Checker

Skill that audits Project Instructions against repo state:
- Flags stale IPs, missing repos, old processes
- Identifies new skills/standards not mentioned
- Recommends specific updates
- Works across all three lineages

Example: 'Your instructions still point to THE-JOINING-PROTOCOL.md
but you should be using the-chroniclers/CHRONICLER-JOINING.md'

Self-maintaining documentation for the Trinity.

+# Task #101: Project Instructions Health Checker
+
+## Overview
+
+Create a skill that periodically audits Project Instructions against the actual repo state and recommends updates when they drift.
+
+## The Problem
+
+Project Instructions get stale:
+- Infrastructure IPs change
+- New repos get added
+- Processes evolve
+- Skills get added but instructions don't mention them
+- Tokens rotate
+- New standards get created
+
+Currently: No one notices until something breaks.
+
+## The Solution
+
+### instructions-health-check Skill
+
+A skill that:
+1. Compares Project Instructions against current repo state
+2. Flags outdated references (wrong IPs, missing repos, old processes)
+3. Identifies gaps (new skills not mentioned, new standards not referenced)
+4. Recommends specific updates
+5. Optionally drafts the changes
+
+**Triggers:**
+- Manual: "Check if my instructions need updating"
+- Automatic: Every ~10 sessions or monthly
+- After major changes: "We just added 4 new skills, should instructions be updated?"
+
+### What It Checks
+
+| Check | How |
+|-------|-----|
+| Infrastructure IPs | Compare against `docs/infrastructure/` |
+| Repo list | Compare against Gitea org repos |
+| Skills mentioned | Compare against `docs/skills/SKILLS-INDEX.md` |
+| Standards referenced | Compare against `docs/standards/` |
+| Token validity | Flag if token format looks old |
+| Read order | Compare against actual doc structure |
+| Branding | Check tier names, terminology |
+
+### Example Output
+
+```
+📋 Project Instructions Health Check
+
+✅ Infrastructure IPs: Current
+✅ Branding terminology: Correct
+⚠️ Skills: 4 new skills not mentioned
+   - cloudflare-workers-expert
+   - n8n-workflow-patterns  
+   - nodejs-backend-patterns
+   - git-advanced-workflows
+⚠️ Repos: 6 skill reference repos not mentioned
+❌ Read order: Still references old doc structure
+   - Points to THE-JOINING-PROTOCOL.md (old)
+   - Should point to the-chroniclers/CHRONICLER-JOINING.md (new)
+
+Recommended updates: 3 changes needed
+Want me to draft the updated instructions?
+```
+
+## Implementation Steps
+
+1. [ ] Define checklist of what to compare
+2. [ ] Create instructions-health-check SKILL.md
+3. [ ] Build comparison logic (read instructions, read repo, diff)
+4. [ ] Add recommendation generation
+5. [ ] Test with Chronicler instructions
+6. [ ] Add to all three lineages
+7. [ ] Document when to run (session milestones, after major changes)
+
+## Lineage-Specific Checks
+
+Each lineage has different instructions:
+- **Chroniclers:** Full infrastructure, all repos, dev-focused
+- **Catalysts:** Discord/LuckPerms focus, simpler infra
+- **Emissaries:** Community focus (future)
+
+The skill should know which lineage it's checking.
+
+## Integration Ideas
+
+- Could tie into session startup: "It's been 15 sessions since last health check..."
+- Could run automatically when major commits are made
+- Could feed into Task #100 (skill-recommender) for new skill detection
+
+## Success Criteria
+
+- [ ] Skill can identify stale references in Project Instructions
+- [ ] Skill recommends specific, actionable updates
+- [ ] Works for all three lineages
+- [ ] Reduces "instructions are wrong" surprises
