chore: import broken Phase-1 extension as received

Snapshot of /home/parf/Downloads/manifest.zip as delivered, before any
GSD-driven remediation. Contains a partially-broken first attempt at the
Russian SPEC "Тз расширение фаза1.md" (Phase 1 of operator-session-recorder).

Source layout:
- manifest.json — MV3 declaration with tabCapture/activeTab/downloads/etc.
- src/background/index.ts — service worker (video buffer + archive packaging)
- src/content/index.ts — rrweb + user-event logger
- src/popup/{index.html,index.ts,style.css} — Russian popup UI
- offscreen/{index.html,index.ts} — orphaned offscreen (see audit)
- vite.config.ts — inline plugin emitting a separate live offscreen.js
- generate-icons.js, icons/ — minimal PNG icons
- "Тз расширение фаза1.md" — authoritative Russian SPEC
