Add Cloud Firestore support and update author name

- Add complete Cloud Firestore module (R/firestore.R) with:
  - CRUD operations: firestore_get, firestore_set, firestore_add,
    firestore_update, firestore_delete
  - Document listing with pagination (firestore_list)
  - Query builder API: firestore_query, fs_where, fs_order_by,
    fs_limit, fs_offset, fs_select, fs_execute
  - Full Firestore data type encoding/decoding

- Add comprehensive tests:
  - 57 unit tests for encoding/decoding and query building
  - Integration tests (skipped without credentials)

- Update documentation:
  - Vignette with Cloud Firestore section and examples
  - README with Firestore in features and code examples
  - NEWS.md with all new Firestore functions
