Summary by cubic

Stabilizes Chrome-driven plugins and makes tests deterministic by consolidating chrome_utils, fixing a tab-setup race, strengthening CDP probing, and standardizing provider hooks/parsers. Also tidies README/CI and replaces optional deps where needed.

• Bug Fixes

  • CI: shorter parallel job names; cache apt packages incl. wget.
  • Chrome: fix tab-setup race by waiting for crawl session/metadata; stronger debug-port probe and ws URL normalization; add helpers (connectToPage, waitForPageLoaded, readCdpUrl/readTargetId, getCookiesViaCdp, waitForCrawlChromeSession, waitForExtensionsMetadata, open/close tab); migrate accessibility, DOM, PDF, infiniscroll, parse_dom_outlinks, navigate/tab, and cookie extraction; raise startup/page-load timeouts to 45s.
  • Tests: use ensure_chrome_test_prereqs; per-plugin conftests; more deterministic local fixtures; enforce hook presence; pre-create output dirs; stabilize extension tests by waiting for metadata; ytdlp deterministic; allow EnvProvider for wget to stabilize detection in CI.
  • Optional deps: favicon uses urllib; RSS lazily imports feedparser; forumdl removes legacy wrapper and SSL flag; fix missing import.

• Refactors

  • Providers/hooks: drop model_rebuild/BinProviderOverrides; standardize click/env parsing; set requires-python to 3.11; README clarifies plugin scope/discovery; get_plugins_dir resolves via file.
  • Parsers/style: tighten URL regex and timestamp parsing across parse_* plugins with broader tests; lint/quote/style normalization.
