/**
 * Browser implementation of {@link IPluginGitService}.
 *
 * `git` is not available in the browser, so plugin contents are reconstructed
 * from the GitHub REST API: `/git/trees/{sha}?recursive=1` for the listing and
 * `/git/blobs/{blob_sha}` for each file's bytes. Both live on `api.github.com`,
 * which is the only GitHub host that handles CORS with auth headers — the
 * `/tarball/` endpoint redirects to `codeload.github.com` (no CORS) and
 * `raw.githubusercontent.com` rejects the OPTIONS preflight forced by
 * `Authorization: Bearer`.
 *
 * Only HTTPS GitHub clone URLs are supported; everything else throws an
 * actionable localized error pointing at desktop or a remote agent host.
 *
 * Per-target metadata is persisted via {@link IStorageService} so `revParse`
 * answers locally, `pull()` skips the re-download when the upstream SHA has
 * not moved, and the persisted SHA feeds `CustomizationRef.nonce` for AHP
 * dedupe.
