Subject: [PATCH 2/6] feat: add import.meta handling for ESM modules

- Remove import.meta from unsupported features list
- Add function to detect import.meta usage in code
- Implement replaceImportMetaObject to inject proper import.meta shims
- Replace esbuild's empty import_meta object with implementation that provides:
  - import.meta.url (file URL)
  - import.meta.dirname (directory path)
  - import.meta.filename (file path)
- Update test-50-esm-unsupported to verify import.meta support
- Add new test-51-esm-import-meta to validate runtime behavior

Remove unnecessary browser-specific code and defensive checks since pkg
targets Node.js executables where __dirname and __filename are always
available.

Subject: [PATCH 5/6] fix: change test file from .mjs to .js to support Node.js
 18

Node.js 18 doesn't support require() of .mjs files even if they are
transformed to CJS. Changed test file extension to .js with "type":
"module" in package.json, and renamed test runner to .cjs to avoid
ESM conflicts. Added test file to .eslintignore since it contains
ESM syntax.

Subject: [PATCH 6/6] refactor: move ESM test file to subdirectory

Moved test-import-meta-basic.js to esm-module/ subdirectory with its
own package.json to avoid conflicts with the test runner which expects
main.js to be CommonJS. This allows the test to work with both the test
runner and Node.js 18.
