chore: upgrade SvelteKit 2 + Svelte 5 (mode compat) + nettoyage packaging

- svelte 5.56, kit 2.70, adapter-static 3, vite 6, svelte-check 4, TS 5.9
- Syntaxe legacy conservée (on:click, $:, export let) — compile en mode compat
- Load RSS : +page.ts → +page.server.ts (XML de 10,9 Mo hors du HTML,
  page podcast 11,9 Mo → 1,5 Mo ; règle au passage le CORS en navigation client)
- package.json : renommé oki-podcast-reader, champs de librairie retirés,
  deps mortes supprimées (changesets, publint, highlights, meta-tags)
- check 0/0, build vert, radio Funkwhale et flux Syntax.fm fonctionnels
