Two related search improvements: 1) Your own live-search results now belong to your Mine feed. A new per-user search_finds table (migration 0030) records each video you surface via your YouTube search (the route inserts them idempotently). The Mine feed becomes 'your non-hidden subscriptions OR your search finds', and the Source filter now applies in Mine too: organic = subscriptions, search = your search finds, all = both (default stays organic, so the main feed is unchanged). The shared Library keeps using the global via_search flag. 2) Feed search ranks by relevance instead of a whole-phrase substring. A custom unaccent_simple text-search config + GIN index (migration 0031) back a YouTube-like fuzzy match: word-order-independent, multi-word AND, prefix on the word being typed, accent-insensitive. A new 'relevance' sort orders by ts_rank; the channel name still matches as a substring. The rank is scaled to an integer so the keyset cursor pages it exactly (a raw float4 breaks paging). _filtered_query returns the rank expr so only the feed list uses it.

Adds the `search_finds` table: a per-user record of which videos a user surfaced via their own
|
|
live YouTube search. This lets "videos I searched for" appear in that user's Mine feed (and the
|
|
Mine Source filter), independent of the global `videos.via_search` flag (which marks a video as
|
|
search-discovered by anyone, for the shared Library's Source filter).
