Subject: [PATCH] test sweep: daemon editor / files residuals (T-91)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- editor_commands_test: insert / replace / set-content / save with no
  active buffer return not-found (covers the _resolveId null branch
  in each handler).
- files_commands_test: files.watch emits a files.changed event when
  a file is created (covers the watcher.stream → events.emit wiring),
  FilesService.atCwd's parent-walk fallback when no .git is found in
  any ancestor.

Coverage: src/daemon/editor_commands.dart 88/100 -> ~95+;
files_commands.dart 64/70 -> 70/70.

Total coverage 92.33% -> 92.44%.
