Reporter (Vicky-2418) saw the artist search fire a separate external-API
search for nearly every letter typed. There WAS a 300ms debounce, but that's
short enough that a deliberately-typed name lands a keystroke per debounce
window, so each letter kicked off (and aborted) a fresh search — noisy in the
logs and wasteful.
Bumped both live-search surfaces that drive the shared SearchController
(external metadata APIs) to 600ms: the /search enhanced input (search.js) and
the global-search widget (downloads.js). 600ms coalesces a name being typed
into one search after the user pauses, while still feeling live. Enter still
triggers an immediate search on both (existing keypress/keydown handlers),
and the per-change abort already cancels stale in-flight fetches.
Frontend-only; both files syntax-clean.
