Separate manual release workflow from CI (#2)

* Separate manual release workflow from CI

* Refactor release workflow with granular job separation

Split release process into distinct jobs (build, github-release, publish-to-pypi)
for better separation of concerns and permission management. Remove workflow_dispatch
inputs from release workflow and update CI workflow to use read-only permissions for
calling the release workflow.

* Use OIDC instead of the API token for PyPI

* Update .github/workflows/release.yml

* Rename .github/workflows/claude-code.yml to .github/workflows/claude.yml

* Fix permissions

* Refactor .github/workflows/claude.yml
