Update publish workflow to use OIDC authentication with provenance

Workflow changes:
- Add permissions for id-token: write and contents: read
- Enable OIDC authentication for npm publishing
- Add --provenance flag for supply chain security
- Add --access public flag to ensure package visibility

Documentation updates:
- Update workflows/README.md with OIDC authentication details
- Explain provenance attestations and security benefits
- Add manual publishing instructions with --access public flag
- Update main README to highlight provenance publishing

Benefits:
- Enhanced security through OIDC authentication
- Supply chain transparency with provenance attestations
- Automatic attestation generation on GitHub Actions
- Better verification of package authenticity

+
+The workflow includes the required permissions:
+```yaml
+permissions:
+  id-token: write  # Required for OIDC authentication
+  contents: read
+```
+
+These permissions allow the workflow to:
+- Authenticate with npm using OIDC
+- Generate provenance attestations for supply chain security
+- Read repository contents for publishing
+
 ## Manual Publishing
 
 If you prefer to publish manually:
 
 ```bash
 npm login
-npm publish
+npm publish --access public
 ```
+
+To publish with provenance locally (requires npm 9.5.0+):
+
+```bash
+npm publish --provenance --access public
+```
+
+**Note:** Provenance generation may not work from all environments. GitHub Actions is the recommended way to publish with provenance.
