- Detect and preserve original indentation (tabs, 2-space, 4-space) and trailing newline style when writing package.json
- Skip write entirely when serialized result matches raw content
- Add scanDirs configuration option to include directories from the default skip list (lib, es, esm, cjs)
- Warn about silently skipped package.json-bearing directories and suggest scanDirs override
- Add comprehensive tests for format preservation, detectJsonFormat utility, and scanDirs behavior
