Files
- Download to the phone (Android's save dialog) or Share — a file, a folder
  as .zip, or a multi-selection. Streamed to disk with progress and Cancel.
- Long-press selects; a selection zips, downloads, shares or deletes. A ⋮
  on every row carries the per-file actions.
- Compress to .zip and Extract, always into a new folder (the server never
  overwrites). Tapping a .zip lists its contents first.
- Export as PDF, made on the phone: markdown (tables, Arabic RTL, repo
  images inlined, mermaid rendered to SVG in a headless WebView because the
  print WebView runs without JavaScript), code as a numbered highlighted
  listing, images, a folder's markdown as one document with contents, and a
  whole chat. Saved to the phone, shared, or put into the repo beside the
  source under a name that never overwrites.

Quality of life
 1. Retry / Edit & resend under a failed run.
 2. Per-chat drafts that survive leaving the chat.
 3. Quick-prompt chips; save your own, long-press to remove.
 4. Screen stays on while a watched run is live (toggle in Settings).
 5. Image preview with pinch and double-tap zoom.
 6. Copy path, and "Ask Claude about this": a new chat, path pre-typed.
 7. Files reopens the folder last used in each project.
 8. Sort by name, date or size; size and age on every row.
 9. Git lists changed files per repo; each opens its own diff with a +/−
    count and Discard for unstaged changes; untracked files show as new.
10. Text size in Settings, app-wide and in the code editor (re_editor
    ignores the app text scale, so it is applied there explicitly).

Fixes
- File and Git actions never read the server's answer. A 200 carrying
  ok:false — a rejected push, a pull that cannot fast-forward — showed
  "Pushed"/"Pulled", and a refused delete said nothing.
- Uploads over 48 MB are refused before sending, with the reason.
- R8 keep rules for printing's android.print bridge; verified in the
  release mapping that PdfConvert and its callbacks keep their names.
- Version 1.4.0+14; Settings no longer claims 1.0.0.

Tests: test/pdf_export_test.dart (8) — span-balanced listing rows, escaping,
language detection, download names, and markdown image paths that cannot
climb out of the project.
