Subject: [PATCH 1/2] feat: Add TypeScript definitions

Adds TypeScript definition files (`.d.ts`) to your project, enabling improved integration and developer experience for TypeScript users.

Key changes:
- Generated type definitions for all modules in `src/` and placed them in the `types/` directory.
- Created `tsconfig.json` to configure TypeScript compilation for declaration generation.
- Refined the main `types/index.d.ts` to ensure accurate types for exported members, replacing `any` types with more specific ones (e.g., for `context`, `getToken`).
- Added a type test file (`test/types.test.ts`) that imports and uses various parts of the library to ensure the types compile correctly.
- Verified that `package.json` includes the `types` field pointing to `types/index.d.ts` and a `build:types` script.

These changes allow TypeScript projects to seamlessly use this package with full type checking and autocompletion support.

Subject: [PATCH 2/2] fix: Prevent Jest from running ts type check file

Renames `test/types.test.ts` to `test/types.check.ts` to prevent Jest from attempting to execute it as a test case. The primary purpose of this file is static type checking using `tsc`, not runtime testing with Jest.

- Renamed `test/types.test.ts` to `test/types.check.ts`.
- Ensured `test/types.check.ts` is included in `tsconfig.json` for continued static type analysis by `tsc`.
- Verified that `npm test` now passes as Jest no longer tries to parse this TypeScript file.
- Confirmed that `npx tsc --noEmit test/types.check.ts` also passes, ensuring the file's type integrity.

This change resolves test failures in CI/CD environments where Jest attempts to run all `*.test.ts` files without appropriate TypeScript transpilation configured for this specific static check file.
