chore: update and streamline publishing workflow for new monorepo structure

Refactors the publishing and release management workflow to support the
dual-generation monorepo architecture:

- Update Changesets configuration to recognize both 1st-gen and 2nd-gen
  workspaces, enabling independent versioning strategies

- Refactor release scripts to delegate to generation-specific publishing
  workflows rather than operating on a flat package structure

- Update CI/CD publishing jobs to build, test, and publish both generations
  with appropriate dependency handling for the shared Core library

- Preserve existing 1st-gen package publishing behavior to avoid disruption
  to current consumers

This workflow enables continuous delivery of improvements to 1st-gen customers
while supporting independent 2nd-gen package releases.
