## Summary by cubic
Prepares `@hexclave/shared-backend` for npm publishing with a proper
build, dual ESM/CJS exports, and bundled types. Also simplifies an
import parsing helper for safer matching.

- New Features
- Configure build with `tsdown`; output CJS/ESM and `.d.ts` to `dist/`
and `dist/esm/`.
- Add export map for `.` and `./config-agent` with `require` and
`default` entries plus types.
- Update publish settings: set `main`/`types` to built files, include
only `dist`, exclude tests, and add `build`, `dev`, `clean` scripts.
  - Add repository field and `tsdown.config.ts`.

- Bug Fixes
- Simplified import specifier parsing in `src/index.ts` to push matches
directly and remove unnecessary error throwing.

<sup>Written for commit 9f18bc019ae452099b719241dd0d4051cad92d09.
Summary will update on new commits.</sup>
