Subject: [PATCH 3/6] =?UTF-8?q?feat(library):=20P2=20=E2=80=94=20YouTube?=
=?UTF-8?q?=20cheap-tier=20processor=20+=20generic=20web-page=20ingestor?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Add YouTubeProcessor for url:youtube items — fetches metadata, thumbnail,
transcript, and chapters via knowledge_fetchers.youtube (yt-dlp). Cheap-tier
only: no video download, just text artifacts for collection indexing.
Add WebProcessor for url:web items — fetches HTML (SSRF-guarded), extracts
readable text via readability-lxml (falls back to tag-stripping). Auto-titles
from
tag.
Both registered in _PROCESSORS dict; run_pipeline dispatches to them
for url:youtube and url:web kinds.
Design doc: docs/design/library-app.md sections 3-4.
Tests: 8 new tests, all 47 library tests pass.
