Test one remote desktop or virtual machine window and report a compatibility row

## What this is

One row for the compatibility matrix (#599), measured in a remote desktop client or a virtual machine app. Uttrflow's dictation, clipboard paste and AI suggestions all depend on how other apps publish text, and the only way to know what a given app does is to try it. No code changes are needed, just one app you already use.

Test a text field *inside* the remote or guest machine, with clipboard sharing on and then off. Copy the invented word `OLD` inside the remote machine first, then dictate. Report what appeared remotely and what the floating button said (#619).

Please say in a comment which app you are taking, so two people do not test the same one. Another app of the same class is a separate row, and welcome on this issue too.

## Where to start

- **Read first:** `CONTRIBUTING.md` for building, and the compatibility matrix issue (MATRIX) for the table you are filling.
- **Build the tool:** `swift build -c release --product uttrflow-dev`.
- **Grant Accessibility:** System Settings › Privacy & Security › Accessibility, add `.build/release/uttrflow-dev`. Accessibility is granted per binary, so the app's own grant does not cover it.
- **Test data:** use invented text only, such as `the quick brown fox` or `support@example.com`. No real names, addresses or messages.

## What to run, in one field of one app

1. Click into the field before each countdown ends.
2. `uttrflow-dev probe surface --seconds 30`: note whether a focused field, value, caret rectangle and text style are reported.
3. `uttrflow-dev insert --via accessibility "one two three four five six seven"`: did it land, get refused, report success and change nothing, or land a moment later?
4. `uttrflow-dev insert --via paste "one two three four five six seven"`: did it land? What did the tool print about confirmation?
5. `uttrflow-dev insert "one two three four five six seven"` (the full route): did the words appear once, twice, or not at all?
6. If you use AI suggestions: accept one suggestion and describe exactly what arrived and where the ghost was drawn.
7. `uttrflow-dev probe ime` while composing with an input method, if you use one.

## What to report

Paste this filled in as a comment, or open a PR adding the row to `Docs/compatibility.md`:

```
App / version:
macOS version / Mac:
Keyboard layout / input source:
Field tested:
Focused field published:
Accessibility write:
Paste:
Paste confirmation:
Full route result:
Caret rectangle:
Value and selection readable:
Marked text published:
Typed completion:
Notes:
```

**Size:** about an hour for one app. One app per comment is plenty, and partial rows are welcome; leave a cell blank rather than guessing.

`make verify` only matters if you open a PR against the doc.

Read CONTRIBUTING.md and compatibility matrix issue #599, then build with `swift build -c release --product uttrflow-dev`. Choose one remote desktop or virtual machine app, run the listed probe and insert commands in one text field with clipboard sharing on and off, and record the results. Done means a completed compatibility row in a comment or Docs/compatibility.md; run `make verify` if opening a documentation PR.
