Add implementation plans and code structure analysis for a 3-phase performance optimization effort. Refactor core modules to reduce timer overhead, consolidate regex usage, extract exec timeout config, add debouncer utility, and streamline server/schema validation.

|
* @fileoverview tmux session manager for persistent Claude sessions.
|
|
*
|
|
* This module provides the TmuxManager class which creates and manages
|
|
* tmux sessions that wrap Claude CLI processes. tmux provides:
|
|
*
|
|
* - **Persistence**: Sessions survive server restarts and disconnects
|
|
* - **Ghost recovery**: Orphaned sessions are discovered and reattached on startup
|
|
* - **Resource tracking**: Memory, CPU, and child process stats per session
|
|
* - **Reliable input**: `send-keys -l` sends literal text in a single command
|
|
* - **Teammate support**: Immutable pane IDs enable targeting individual teammates
|
|
*
|
|
* tmux sessions are named `codeman-{sessionId}` and stored in ~/.codeman/mux-sessions.json.
|
|
*
|
|
* Key features:
|
|
* - `send-keys 'text' Enter` sends literal text in a single command
|
|
* - `list-sessions -F` provides structured queries
|
|
* - `display-message -p '#{pane_pid}'` for reliable PID discovery
|
|
* - Single server architecture
|
|
*
|
|
* @module tmux-manager
