feat(mercari): Phase 2 — MercariAdapter with Xvfb stability fixes
Implements full Mercari scraping support for the trust-scoring pipeline:
- `app/platforms/mercari/` — new MercariAdapter (scraper-based), scraper
(parse_search_html / parse_listing_html), and __init__
- `app/platforms/__init__.py` — adds "mercari" to SUPPORTED_PLATFORMS
- `api/main.py` — platform routing: _make_adapter, OR-group guard, seller
lookup, BTF/Trading API guards all parameterised by platform
- `web/src/views/SearchView.vue` — enables Mercari tab in platform picker
BrowserPool stability fixes (browser_pool.py):
- Add -ac flag to Xvfb (disables X11 auth requirement in Docker containers)
- Shift display counter from :100-:199 to :200-:399 (avoids ghost kernel
socket conflicts with low-numbered displays)
- Add wait_for_selector / wait_for_timeout_ms params to fetch_html,
_fetch_with_slot, _fetch_fresh
- Add time.sleep(0.3) in _fetch_fresh after Xvfb start (was missing)
Mercari scraper fix:
- Remove sortBy=SORT_SCORE from build_search_url — that param is deprecated
on Mercari and causes an empty 85KB response instead of search results
Probe + debug scripts in scripts/:
- probe_mercari.py — standalone Cloudflare bypass test
- debug_fetch_fresh.py — pool simulation diagnostic
Trust signal coverage: feedback_count, feedback_ratio partial score
(account_age_days, category_history absent = score_is_partial=True).
get_completed_sales stubbed for Phase 3.
Tracks: snipe#53 (pool thread-safety fix, follow-up)
