feat(app): surface active SSH usage and add connect-time Playwright toggle

[skulidropek]

Summary

• show runtime state and active SSH session count in Stop container / Delete project selectors
• add safe confirmations for stop/delete when active SSH sessions are detected
• add Select project -> Connect toggle (P) to choose enabling MCP Playwright before SSH
• ensure terminal cursor is visible before interactive SSH handoff (menu connect + clone/create auto-SSH)

Fixes #47
Fixes #33
Fixes #3

Proof (logic works)

Visible fragments in TUI:

> 1. org/repo (PR#47) [running, ssh=2]

Enter = select + SSH, P = toggle Playwright MCP (on), Esc = back

Playwright MCP: will be enabled before SSH (P to disable).

Stop/Delete confirmation now explicitly includes active SSH usage before destructive actions.

Automated tests

Added tests:

• packages/app/tests/docker-git/menu-select-connect.test.ts
  • verifies ON flow executes enable before connect
  • verifies OFF flow skips enable
  • verifies toggle key parsing (P)
  • verifies connect hint reflects ON/OFF state
• packages/lib/tests/usecases/terminal-cursor.test.ts
  • verifies cursor show escape is emitted in interactive TTY
  • verifies no write in non-interactive mode

✓ tests/usecases/terminal-cursor.test.ts (2 tests)
