Krzysztof kuhy Rudnicki 41deb90324 feat: add interactive web UI for backlog completion planning
Adds a React/TypeScript frontend (web/) with a Python stdlib HTTP server
backend.  The UI mirrors the CLI `stats` command in the browser, with
real-time sliders for ProtonDB rating, HLTB confidence thresholds, daily
play time, per-game time cap, playtime mode, no-HLTB-data fallback, and a
target-date planner.  A parity badge confirms the client-side totals
reproduce the CLI defaults exactly (786 / 67031.1h / 143017.2h / 238447.9h).

Python side:
- `_web_dataset.py`: offline projection of HLTB/ProtonDB/snapshot caches
  into a compact, secret-free JSON payload; 100% branch coverage
- `_web_server.py`: zero-dependency stdlib HTTP server serving the built
  Vite bundle and the /api/dataset endpoint; 100% branch coverage
- `main.py`: new `serve` command wiring

Frontend (Vitest + RTL, 100% branch coverage enforced):
- TypeScript port of ProtonDB compound rating rule with full parity
- Pure client-side filtering via estimate.ts (no server round-trips)
- SVG completion timeline chart, sortable/searchable game table
- Steam dark theme; responsive layout

Pre-commit: adds `vitest-coverage` hook at pre-push stage requiring 100%
branch coverage on the React codebase.
