Auth: `getSession()` in a SvelteKit load function races with Supabase's async
localStorage init and can return null for a valid session, triggering a spurious
login() redirect. Moved auth redirect to (app)/+layout.svelte via $effect, which
correctly waits for onAuthStateChange to fire. Also fixed collective data never
loading on page refresh (INITIAL_SESSION event, not SIGNED_IN).
PWA: SvelteKit blocks Workbox imports in src/service-worker.ts, preventing
@vite-pwa/sveltekit from finding the compiled SW output. Switched to generateSW
strategy (plugin auto-generates the SW). Custom SW deferred to Fase 2b using
src/sw.ts (a filename SvelteKit does not intercept).
Docs: added gotchas 6–8 to CLAUDE.md covering both root causes so they are not
reintroduced. Updated plan/fase-2b with the sw.ts workaround note.
