chore: migrate from tsup to tsdown (#1303)

* chore: migrate from tsup to tsdown

tsup has been discontinued (https://github.com/egoist/tsup) and tsdown
is the recommended replacement that is much faster.

Changes:
- Replace tsup with tsdown v0.18.0 dependency across all packages
- Create new tsdown.config.ts files for all 8 packages
- Update build scripts in package.json files
- Update Dockerfile.manage-api-test to reference tsdown
- Add custom rawPlugin for agents-run-api to handle ?raw XML imports
- Use regex pattern for noExternal to properly bundle subpath imports
- Set hash: false for predictable DTS file paths
- Add outExtensions config to maintain .js/.cjs file extensions

Closes: PRD-5456

* add changelog
