refactor: implement per-conversation tmux sessions and command-based MCP tools

Browse Source 
This commit implements isolated tmux sessions for each conversation and
refines the terminal MCP tools to use consistent command terminology.

**Per-Conversation Tmux Sessions:**
- Each Session now creates its own Terminal MCP client with conversation ID as tmux session name
- Complete isolation: commands from different conversations don't interfere
- Automatic cleanup: tmux session killed when conversation ends
- Updated getAllTools() to accept custom terminal tools per session
- Session.cleanup() now async to properly await tmux session termination

**Command-Based MCP Tools:**
- Removed old terminal-based tools (list_terminals, create_terminal, etc.)
- Kept only command-based tools (execute_command, list_commands, etc.)
- Updated kill_command to accept multiple command IDs for batch cleanup
- Fixed bug where all commands showed same metadata (working directory, command)
- Added window-specific option storage using set-window-option/show-window-options

**Bug Fixes:**
- Fixed listCommands() showing wrong working directory and command for dead commands
- Stored command metadata as tmux window options for proper retrieval
- Enhanced test to verify multiple commands retain unique metadata

**Testing:**
- Added comprehensive test suite with 26 passing tests
- All tests verify command execution, capture, interaction, and cleanup
- TypeScript: no errors
- Backward compatibility maintained with global singleton fallback
