Fix release workflow failure caused by Biome formatting drift in package.json

[Copilot]

The release GitHub Actions job was failing during bun run lint because Biome detected a formatting violation in package.json. This PR applies the minimal formatting correction so the release pipeline can proceed.

• Root cause

  • biome check failed on package.json due to a trailing blank line at EOF.

• Change

  • Removed the extra trailing newline in package.json (no runtime/code-path changes).

• Why this is minimal

  • No source logic, workflow logic, or dependency changes.
  • Strictly aligns repository metadata formatting with Biome expectations.
