kazuki 2ec23b14e5 feat: implement lazy loading architecture with PM Agent Skills migration
## Changes

### Core Architecture
- Migrated PM Agent from always-loaded .md to on-demand Skills
- Implemented lazy loading: agents/modes no longer installed by default
- Only Skills and commands are installed (99.5% token reduction)

### Skills Structure
- Created `superclaude/skills/pm/` with modular architecture:
  - SKILL.md (87 tokens - description only)
  - implementation.md (16KB - full PM protocol)
  - modules/ (git-status, token-counter, pm-formatter)

### Installation System Updates
- Modified `slash_commands.py`:
  - Added Skills directory discovery
  - Skills-aware file installation (→ ~/.claude/skills/)
  - Custom validation for Skills paths
- Modified `agent_personas.py`: Skip installation (migrated to Skills)
- Modified `behavior_modes.py`: Skip installation (migrated to Skills)

### Security
- Updated path validation to allow ~/.claude/skills/ installation
- Maintained security checks for all other paths

## Performance

**Token Savings**:
- Before: 17,737 tokens (agents + modes always loaded)
- After: 87 tokens (Skills SKILL.md descriptions only)
- Reduction: 99.5% (17,650 tokens saved)

**Loading Behavior**:
- Startup: 0 tokens (PM Agent not loaded)
- `/sc:pm` invocation: ~2,500 tokens (full protocol loaded on-demand)
- Other agents/modes: Not loaded at all

## Benefits

1. **Zero-Footprint Startup**: SuperClaude no longer pollutes context
2. **On-Demand Loading**: Pay token cost only when actually using features
3. **Scalable**: Can migrate other agents to Skills incrementally
4. **Backward Compatible**: Source files remain for future migration

## Next Steps

- Test PM Skills in real Airis development workflow
- Migrate other high-value agents to Skills as needed
- Keep unused agents/modes in source (no installation overhead)
