Subject: [PATCH] Switch npm publish to OIDC Trusted Publisher
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The @bitmovin/cli npm package is now configured with a Trusted Publisher
binding to bitmovin/cli :: pack.yml (OIDC). Replace the long-lived NPM_TOKEN
auth on the publish-npm job with the OIDC flow:

- Add permissions: id-token: write so the workflow can mint an OIDC token
- Drop NODE_AUTH_TOKEN and setup-node's registry-url (no .npmrc auth needed)
- Upgrade npm to >= 11.5.1 (Node 20 ships with an older npm)
- Publish with --provenance for sigstore-attested provenance

Also remove the daily NPM_TOKEN expiry-check workflow and the expiry tracker
file — neither is needed with ephemeral OIDC tokens.

Manual follow-ups for a maintainer:
- Delete the NPM_TOKEN repo secret
- Revoke the legacy granular token on npmjs.com

-
-          1. On npmjs.com → **Access Tokens → Generate New Token → Granular Access Token**:
-             - Packages and scopes: \`@bitmovin/cli\` (read + write)
-             - **Bypass two-factor authentication: ON**
-             - Expiration: 90 days
-          2. Store it as the repo secret:
-             \`\`\`
-             printf '%s' '<new-token>' | gh secret set NPM_TOKEN --repo $GITHUB_REPOSITORY
-             \`\`\`
-          3. Bump the expiry date in \`.github/npm-token-expiry.txt\` and commit on \`main\`.
-          4. Revoke the previous token on npmjs.com.
-          5. Close this issue.
-
