refactor(vcs): mirror Composer interfaces; rename get_local_changes

- Rename `local_changes` → `get_local_changes` to match Composer's
  `getLocalChanges`
- Add `is_change_report`, `is_vcs_capable_downloader`,
  `is_dvcs_downloader` trait methods to replace PHP `instanceof` checks
- Add `VersionParser` stub to keep `VersionGuesser::new` signature
  compatible with Composer's constructor
- Add `ArrayDumper` in status.rs mirroring
  `Composer\Package\Dumper\ArrayDumper`; expand `build_package_config`
  to include all fields that `VersionGuesser` inspects
