Reverts all seven commits of #119381 (59c54c78..476ff4dd), which
re-landed the native card-based Skills/Plugins catalog browser after it
was reverted twice (#113037 reverting #112669, #115787 reverting
#113128). Capabilities -> Skills and Plugins return to the list/detail
tabs with the embedded catalog picker they had before #119381.
Removed with it:
- Desktop catalog/ module (browser, cards, detail dialog, filters,
reels/masonry, install switch) and skill deep-link install
(hermes://skill/install); skills/embedded-hub-picker.tsx comes back.
- apps/shared catalog-browse.ts and catalog-install.ts.
- The `catalog` i18n namespace in every locale (+ regenerated
locales/_keys.desktop.json); the two i18n pack tests and the keys
test now exercise connectorsPage.searchPlaceholder instead.
- Website /skills "Open in Hermes Desktop" skill links and the
extract-skills install identifiers; docs return to the pre-#119381 text.
- Later fixes that only patched the reverted catalog code go with it:
5832a6eb93 + 7aba2cbbe9 (catalog download deadline),
9e63cdc4b8 (catalog lookalike rows), c756986db2 (catalog counts),
the catalog half of c13232e90c / f265273347.
Kept on purpose (later work that depends on code #119381 introduced):
- DialogContent `chrome` / `overlayClassName` / nested-dialog layering
(the image lightbox uses them).
- vitest.setup.ts / src/test/jsdom.ts stubs (other suites rely on them).
- Kanban toolset wiring on the Plugins Desktop switch (cd30fdadf6,
7ca2f5665f) and its tests, the `hermes_not_connected` server tone,
the SearchField flex-1 fix, skill provenance helpers. SkillDetail shows
a provenance pill only for agent/hub skills, since the pre-#119381
labels have no `external` entry.
