Mirrors PR #1464 (list-tweets) and the timeline/search/tweets/likes/thread
family: spread `...extractMedia(legacy)` into the row and surface
`has_media` + `media_urls` columns. Pure parity, no behavior change for
existing callers — media keys do not collide with the original columns.
- bookmarks.js: import `extractMedia` from ./shared.js, spread into
extractBookmarkTweet row, append columns, export __test__.
- bookmark-folder.js: same change on extractFolderTweet, export
extractFolderTweet via __test__.
- bookmarks.test.js (new): baseline + photo + video + entities-only
fallback + dedup + envelope + empty-envelope (8 tests).
- bookmark-folder.test.js: update existing baseline expectation with
has_media/media_urls, add 3 new media tests (photo / mp4 / no-media).
- cli-manifest.json: regenerated; only the two `columns` entries change.
Reverse-validated: tests fail when extractMedia spread is removed.
Audits unchanged: typed-error-lint 189/189, silent-column-drop 102/103
(pre-existing main resolution noted but not consumed here).
