Add Claude hooks integration for AnviLLM

- Created install-claude-hooks.sh to merge hooks into existing settings.json
- Updated mkfile to use merge script instead of overwriting settings.json
- Made agent name configurable via CLAUDE_AGENT_NAME env var
- Added Claude agent configuration and hook scripts
- Removed unused NewClaudeWithContinue/NewClaudeWithResume functions
