fix(type-check): unblock two more pre-existing failures

After yesterday's type-check cascade repair (c34175afa), the root
\`pnpm run type-check\` progressed through 5 more packages but still
stopped on two pre-existing failures:

- \`services/mana-media\` delivery route: \`c.body(transformedBuffer)\`
  passed a Node \`Buffer<ArrayBufferLike>\`, but Hono 4.7 types the
  body argument as \`Uint8Array<ArrayBuffer>\` (strict — no
  ArrayBufferLike). \`Uint8Array.from(buf)\` gives a clean copy with a
  fresh \`ArrayBuffer\` backing that the strict type accepts. Runtime
  cost for a handful of KB per image transform is negligible next to
  the Sharp pipeline that produced the buffer.
- \`packages/shared-llm\`: same rune issue as local-stt + local-llm —
  \`store.svelte.ts\` uses \`$state\` and transitively pulls in
  \`local-llm/src/svelte.svelte.ts\`. Plain tsc can't resolve Svelte 5
  runes. Same treatment: \`type-check\` script explicitly skips with a
  message pointing at svelte-check.

Root \`pnpm run type-check\` now reaches \`@context/mobile\`, which has
real code-level type errors (adapter shape mismatches, an RN event-
handler typing drift, and a deleted Supabase module still imported by
\`utils/supabaseTest.ts\`). Those need domain changes, not config
tweaks — out of scope for this repair pass.
