Use package.json as the single source of truth for CLI version

[Copilot]

ol --version was reporting a stale hardcoded value from src/index.ts instead of the package’s actual release version. This caused version output drift whenever package.json was updated.

• Version source correction

  • Updated CLI program metadata in src/index.ts to read version from package.json rather than a literal string.
  • Aligns runtime version output with published package metadata.

• Impact

  • ol --version now reflects the current package version consistently across releases.

import packageJson from '../package.json' with { type: 'json' }

program
	.name('ol')
	.version(packageJson.version)
