Drop 'Cursor' from plugin descriptions in the marketplace manifest and
per-plugin manifests so they read correctly in any agent client, and
resync the README table that mirrors them.

Completes the third_party grouping so all vendor MCP integrations live in
one place. Updates marketplace source paths, root README links, and the
tree/main homepage URLs in each manifest.
Safe for already-published plugins: the indexer keys plugin identity on
(marketplaceId, name), so a re-index updates gitPath in place rather than
creating a new row, and deprecation is name-based too. Logos stay relative
to the plugin root and re-resolve against the new basePath.
