Zebratic 78ebc4fffd Add Playwright-based smoke test scripts
scripts/smoke.js, scripts/probe.js, scripts/probe-inject.js,
scripts/probe-minimal.js, scripts/smoke-final.js

The smoke test verifies the Beat Pocket extension loads and injects into
beat-battle.net:

  1. Service worker registers (manifest valid, MV3 wiring works)
  2. Content script runs (creates #bbp-host element on document.body)
  3. No JS errors thrown on the page
  4. Site renders normally (PLAY button still visible)

Why Playwright instead of raw --load-extension:
  - Google Chrome refuses --load-extension on the command line
  - Chromium full build accepts it but hangs under --virtual-time-budget
  - Playwright's launchPersistentContext properly initializes extensions
    in headless mode and gives a clean Chromium without the GCM/dbus noise
  - The bundled Chromium is at
    /root/.cache/ms-playwright/chromium-1208/chrome-linux64/chrome

Run with: node scripts/smoke-final.js (after npm install)

Probe results from this session:
  - [final:dom] #bbp-host is appended to body via ensureHost()
  - [final:errors] 0 page errors
  - [final:console] 0 extension-related console lines (expected: silent
    happy path; logs only on phase transitions)
