Usage:
  ./scripts/create-github-release.sh <version> [--dry-run]

Examples:
  ./scripts/create-github-release.sh 2026.318.0
  ./scripts/create-github-release.sh 2026.318.0 --dry-run

Notes:
  - Run this after pushing the stable tag.
  - Resolves the git remote automatically.
  - In GitHub Actions, origin is used explicitly.
  - If the release already exists, this script updates its title and notes.
