Pull request overview

Updates the production Python deployment workflow to remove the requirement for manually entering a release tag on workflow_dispatch, by defaulting to the ref tag that triggered the run and adding a guardrail to fail fast when no tag can be determined.

Changes:

• Made release-tag optional for manual runs and defaulted the deploy tag to github.ref_name when appropriate.
• Added a validate-release-tag job to ensure the workflow has a resolvable tag before attempting publication.
• Wired both Conda and PyPI reusable-workflow calls to depend on the validation step.

• publish-conda is a hyphenated workflow_dispatch input, so it should be referenced with bracket notation in expressions (otherwise the - can be parsed as an operator).

    if: ${{ github.event_name == 'release' || github.event.inputs.publish-conda == 'true' }}
