feat(library): browse local index race and catalog paths (#847)

* feat(library): race local index vs network on browse text search

Wire Artists, Composers, Tracks, and SearchResults to parallel local FTS
and network search3 with graceful fallback when remote fails while the
index is ready.

* feat(library): local browse for albums/artists and dev race logging

Serve All Albums and Artists catalog from the local index when ready,
with network fallback. Log browse text-search race outcomes to DevTools
(`[psysonic][library] browse-race …`) including winner, timings, and hits.

* docs(changelog): note PR #847 browse local index race and catalog paths

* refactor(library): unify DevTools search log format

Live Search, Advanced Search, and browse races emit one-line
`search [surface] …` entries via formatLibrarySearchLine (DEV only).
