fix(type-check): repair silently broken per-package type-check scripts

Yesterday's postinstall fix (\`d1d37749f\`) removed the \`|| true\`
guards, which in turn exposed that \`pnpm run type-check\` at the
root had been red for a long time but nobody noticed. Several per-
package scripts were genuinely broken:

- \`@mana/test-config\`: \`vitest.config.base.ts\` and \`.svelte.ts\`
  pass \`all: true\` to the coverage block. Vitest 4 removed that flag
  (including uncovered files is now the default), so tsc reports
  \`'all' does not exist in type 'CoverageOptions'\`. Removed both.
- \`@mana/credits\`: \`tsconfig.json\` include glob had
  \`"src/**/*.svelte"\`, which makes tsc try to parse .svelte files
  as TS source. It can't. Removed .svelte from include; added
  \`"exclude": ["src/web/**"]\` — the web consumer layer is checked by
  svelte-check in the apps that import it, not here.
- \`@mana/local-stt\` + \`@mana/local-llm\`: ship \`svelte.svelte.ts\`
  files that use Svelte 5 runes (\`$state\` etc.). Plain tsc has no
  rune support — \`$state\` is not a name it knows about. Both
  packages' \`type-check\` scripts now explicitly skip with a message
  pointing at svelte-check as the right tool. The rune code is still
  type-checked by svelte-check when a consumer app runs \`pnpm check\`.
- \`@manavoxel/shared\`: was missing its \`tsconfig.json\` entirely,
  so the \`type-check\` script ran tsc with no config, which dumped
  the CLI help and exited non-zero. Added a minimal bundler-mode
  tsconfig matching the pattern used by sibling packages.

\`pnpm run type-check\` now goes further than it has in months —
next failure is a real pre-existing Hono type mismatch in
\`services/mana-media/apps/api/src/routes/delivery.ts\` (Buffer vs
c.body signature), which is out of scope here and needs a proper
code fix, not a config fix.
