Greptile Summary

This PR updates the Google Closure Compiler from version 20230206 to 20251111 to support newer OpenJDK versions. The changes include:

• Upgraded google-closure-compiler dependency and updated CI to use Java 21
• Converted Closure Compiler imports to ESM dynamic imports (await import())
• Added dynamic_import_alias: 'import' configuration flag
• Regenerated Fizz runtime inline code strings with the newer compiler

The newer Closure Compiler produces slightly different minified output with modernized comparison syntax (e.g., a === b instead of b === a, x !== y instead of y !== x), but the logic remains functionally equivalent. All changes are consistent with the stated goal of supporting newer OpenJDK.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The changes are straightforward dependency updates with corresponding configuration adjustments. The conversion to ESM imports is correct, the Java version upgrade is necessary for the new Closure Compiler, and the regenerated inline code strings show only stylistic differences in minified output while maintaining functional equivalence. The PR is a mirror of Update closure compiler facebook/react#35303 and follows established patterns.
• No files require special attention
