alonso.torres 18cdf3b22a ✨ Sync the components a sync changes in the same commit
Decision (c) of the component contract, after a fix that made the sync of a
library file reach that file at all (Phase 3c).

- Commit the sync of a library file to that file.

  An update of the main of a library component, made from a copy in the
  file, syncs the copies of the component in the file and in the library.
  The changes of a sync carry no file id, so the commit took the current
  file's: the library's copies, among them those its other mains nest, were
  written to pages the current file does not have, and never changed (F19).
  A sync now commits to the file it syncs.

  workspace-remote-cascade-test: an update of the main of a library
  component reaches the copy of it that another library main nests.

- Sync the components a sync changes in the same commit.

  Decision (c) of the component contract: a sync reaches the copies of the
  components it changes, until none is left, in one commit. A sync of a file
  changed the mains of the components that nest the synced copies, and the
  component watcher synced those in a commit of its own, one level per pass,
  so the file stayed partly synced in between; the watcher only watches the
  current file, so a sync of a library file stopped at its first level
  (F19).

  common: generate-sync-file-cascade syncs a file as
  generate-sync-file-changes does, then the copies of each component of the
  file that the sync changed, one per pass, applying each pass to the file
  data, until none is left (generate-sync-components-cascade). The
  composable runner, the benchmark and the golden master use it.

  frontend: sync-file commits the whole cascade at once. When it syncs a
  library file, it then syncs the copies in the current file of the library
  components the cascade changed.

  workspace-remote-cascade-test: an update of the main of a library
  component, made from a copy in the file, reaches the file's copy of a
  library component whose main nests it. The common golden master records
  fewer changes undone in case W: a cascade is one change set.
