Initial commit: Ajarbot with optimizations

Features:
- Multi-platform bot (Slack, Telegram)
- Memory system with SQLite FTS
- Tool use capabilities (file ops, commands)
- Scheduled tasks system
- Dynamic model switching (/sonnet, /haiku)
- Prompt caching for cost optimization

Optimizations:
- Default to Haiku 4.5 (12x cheaper)
- Reduced context: 3 messages, 2 memory results
- Optimized SOUL.md (48% smaller)
- Automatic caching when using Sonnet (90% savings)

+# Adapter Development Skill
+
+You are helping develop messaging platform adapters for ajarbot using the OpenClaw-inspired architecture.
+
+## When invoked
+
+1. **Analyze the request**: Understand what adapter work is needed
+2. **Check existing patterns**: Review `adapters/slack/` and `adapters/telegram/` for patterns
+3. **Follow the base contract**: All adapters must implement `BaseAdapter` from `adapters/base.py`
+4. **Test the implementation**: Suggest tests and validation steps
+
+## Key files to reference
+
+- `adapters/base.py` - Base adapter interface
+- `adapters/runtime.py` - Runtime integration
+- `adapters/slack/adapter.py` - Slack Socket Mode example
+- `adapters/telegram/adapter.py` - Telegram example
+- `README_ADAPTERS.md` - Architecture documentation
+
+## Common tasks
+
+### Create new adapter
+1. Create `adapters/<platform>/adapter.py`
+2. Implement required methods from `BaseAdapter`
+3. Define capabilities (threads, reactions, max length, etc.)
+4. Add to `bot_runner.py`
+5. Update config template
+
+### Debug adapter issues
+1. Check `validate_config()` returns true
+2. Verify credentials format
+3. Test `health_check()` method
+4. Review async event handler registration
+5. Check message chunking logic
+
+### Update existing adapter
+1. Read current implementation
+2. Understand the change request
+3. Follow existing patterns
+4. Preserve backward compatibility
+5. Update documentation
+
+## Security considerations
+
+- Never log credentials or tokens
+- Validate all user input before processing
+- Use platform-specific rate limits
+- Handle errors gracefully
+- Respect user allowlists
+
+## Output format
+
+Provide:
+1. Clear explanation of changes
+2. Code implementation
+3. Configuration updates needed
+4. Testing steps
+5. Documentation updates
