// "we want this to work right out of the box": the 190MB dictation model is bundled so the first fn
// press transcribes instead of waiting on a download. Two silent paths defeated that, and both end
// in a build that looks fine and ships without the model, saying so only in a log line.
//
//   1. The model is read from electron/whisper/, which is GITIGNORED, and releases are cut in a
//      detached worktree, which by definition has no gitignored files.
//   2. The staging cache exits early on a staged BINARY alone, so any publish rerun skipped the
//      model block entirely. Measured on the 1.7.9 script with the model sitting right there:
//      "already staged at v1.7.6, skipping", exit 0, zero model files staged.
