fix: disable crates.io publishing until ready

- Comment out cargo publish step in release workflow
- Prevents accidental publishing without proper setup
- Add TODO comment for future activation
- Maintains release workflow for testing and validation

Publishing can be enabled later when crates.io account and token are configured.
