chore: Symlink commontools.d.ts from commontools/api

[jsantell]

Summary by cubic

Symlinked commontools.d.ts to commontools/api to keep types in sync and remove the custom type build step. This simplifies the static package and reduces maintenance.

• Refactors
  • Replace generated types with a symlink: assets/types/commontools.d.ts -> ../../../api/index.ts
  • Remove compile-api-types deno task and its script
  • Clean up deno.json scripts
  • Drop CI check for derived artifacts in .github/workflows/deno.yml
