Fix Sentry noise: rate-limit Steam API, fix headless browser launch, downgrade test logging

claude · claude · commit 39d4fe53d534 · 2026-03-28T06:58:21.000-06:00
Three root causes for spurious Sentry errors:

1. Steam API 429/403: Zero rate limiting on Steam Store API calls meant
   a single search could fire 65+ unthrottled requests. Added 1 req/sec
   throttle matching Steam's undocumented limits.

2. Browser launch on headless Linux: Environment.UserInteractive returns
   true on headless Linux (it's Windows-centric). Now checks for DISPLAY
   or WAYLAND_DISPLAY before attempting to open a browser.

3. Download client test failures: All test/validation methods logged at
   Error level, triggering Sentry for expected scenarios (wrong creds,
   SSL mismatch, server down). Downgraded to Debug since the user gets
   the validation failure in the UI — these aren't bugs.
