refactor: enhance artifact system, security, and terminal command handling

- Add basic HTTP authentication (express-basic-auth)
- Improve artifact tool with better source type handling (command_output, file, text)
- Update agent prompt with clearer artifact usage patterns
- Refactor tmux command execution to use execFile for safer argument handling
- Add UI cancellation capability for in-progress operations
- Switch session dumps to use util.inspect for better formatting
- Update artifact tool schema to require title parameter first
