P0: Add workflow_dispatch to release workflow + manual rerun support

[Kinin-Code-Offical]

[Kinin-Code-Offical]

Plan:

• Add workflow_dispatch trigger with a required tag input for manual reruns.
• Resolve a single RELEASE_TAG used for checkout, version check, asset cleanup, and release upload.
• Ensure release step runs for both tag pushes and workflow_dispatch.

Risks:

• Manual runs with a non-existent tag will fail checkout/version check.

Tests:

• npm ci
• npm run lint
• npm test
• npm run build
• npm run package
• npm run smoke:exe
• npm run installer
• npm run stage
