- Built-in editor (default): large modal with monospace textarea, Cmd+S save,
dirty guard; reads/writes through the provider streams so it works on local
and remote files identically (2MB cap with a friendly error)
- External editor: remote files download to appDataDir/edits/<id>, open via
macOS `open -a`, the temp DIR is watched (survives atomic rename-saves) and
every save enqueues a normal upload job (progress/errors in the transfer
list); watchers + temp dirs are cleaned when the session disconnects
- Editor setting: Built-in | Custom with a NATIVE app picker (electrobun
openFileDialog, /Applications, .app filter) and reset-to-default
- Leftover temp files from a crash prompt for cleanup at boot
- F4, toolbar button (mynaFileText), and File > Edit File (Cmd+E) menu entry
- README: feature notes + Portability notes (open/start/xdg-open seam
documented in code and README per user request)
Verified headless against the box: sftp read/write roundtrip incl. UTF-8,
size cap, watch->save->auto-upload->remote-updated, session cleanup, orphan
listing and clearing.
