/**
 * pi-bundle — The essential Pi extension bundle by artale
 *
 * One install, 10 best extensions:
 *   pi-compact     — smart context compaction
 *   pi-lean        — truncate verbose output
 *   pi-rewind      — auto-checkpoint + undo
 *   pi-tokens      — real-time token tracking
 *   pi-memory      — persistent project memory
 *   pi-watch       — #pi! file watcher
 *   pi-procs       — background process manager
 *   pi-caffeinate  — keep machine awake
 *   pi-stash       — git stash for prompts
 *   pi-context     — context window warnings
 *
 * This extension itself just provides /bundle info.
 * The actual extensions are installed as dependencies.
