feat: listContents + selective extract APIs

[cursor]

Motivation

Users currently leave for other libraries (e.g. react-native-zip-stream) when they need to inspect a ZIP before extracting, or extract only some entries. See e.g. SO: Read zip file content before unzipping.

Proposal

listContents(source: string, charset?: string): Promise<ZipEntry[]>

Return archive metadata without extracting:

type ZipEntry = {
  path: string;
  size: number;           // uncompressed
  compressedSize: number;
  isDirectory: boolean;
  isEncrypted: boolean;
};

unzipFiles(source, destination, entries: string[], charset?: string): Promise<string>

unzipFilesWithPassword(source, destination, entries: string[], password: string): Promise<string>

Extract only the listed entry paths (files and/or directories). Paths that escape the destination must be rejected (Zip Slip).

Acceptance criteria

• Works on iOS and Android with matching entry shapes
• Password-protected archives supported via the *WithPassword variant
• Zip Slip rejected for selective extract the same as full unzip
• Progress events emitted for selective extract
• TypeScript types + TurboModule spec updated
• Jest mocks updated; playground coverage for the new APIs
