chore: Enable verbatimModuleSyntax and fix type imports

- Remove test-bun CI job (Vitest tests don't run on Bun's test runner)
- Add verbatimModuleSyntax to tsconfig to catch type export issues at build time
- Convert all type-only imports to use `import type` syntax

This ensures that type exports are properly marked, preventing runtime
errors when the code is bundled or run with stricter module systems.
