bvandeusenandClaude Opus 5.5 94a9c8cbe3 chore(deps): SvelteKit 3 with adapter-static 4 and TypeScript 6, full-tree npm audit (#5021)
Merges Renovate's kit 3 (PR #149) and adapter-static 4 (PR #148) bumps,
plus the migration they need. The mechanical part is `sv migrate
sveltekit-3`, run one task at a time and reviewed:

- svelte.config.js is gone. Its options move into sveltekit() in
  vite.config.ts, exported as kitOptions so vitest.config.ts runs the
  same kit setup, including the $test-utils alias the tests import.
- $lib becomes #lib through package.json "imports". There is no
  src/lib/index, so only the "#lib/*" entry is kept.
- tsconfig extends $app/tsconfig.
- Peer floors raised to kit 3's requirements: svelte ^5.57.1, vite
  ^8.0.12, svelte-check ^4.7.5.

By hand, from the codemod's list of non-automated tasks:

- goto's replaceState option is now replace; keepFocus becomes
  reset: false. For the search typeahead, reset: false also stops the
  scroll-to-top, which is wanted while typing.
- The test setup mocks drop pushState/replaceState and $app/paths
  base/assets, which kit 3 removed, and mock refreshAll in place of
  invalidateAll.
- The other flagged files only read page.url or goto internal routes,
  so they needed no change.

TypeScript goes to ^6, not the ^7 Renovate offers: kit 3 declares
typescript ^6 as a peer and svelte-check 4.7 accepts ^5 || ^6. Move to
7 once both accept it.

With Tailwind 4 and kit 3 in, `npm audit` on the whole tree reports 0,
so the web lane now audits every dependency rather than only what
ships to browsers.

// Inbound server events over SSE (#968). The web client's OUTBOUND half
// (play events) lives in player/events.svelte.ts; this is the inbound
// listener it never had. Today it reacts to `playlist.system_rebuilt` — the
// daily 03:00 rebuild or a manual refresh — by invalidating the home +
// system-playlist query caches so a tab left open across the rebuild stops
// serving yesterday's snapshot (the stale-browse-view bug). Active playback
// self-heals separately on the failure path (store.handleLoadFailure); we
// deliberately do NOT yank a playing queue here — that would interrupt a
// mid-song listen to restart the new mix at track 0.
// Monotonic rebuild counter (#980). Bumped on every playlist.system_rebuilt.
// An open system-playlist DETAIL page can't be invalidated in place (its id
// rotates on rebuild — a refetch would 404), so instead it watches this
// counter and offers a "this mix was refreshed → Refresh" affordance that
// re-resolves the variant to the new playlist.
