Buttons that run your own scripts, written by hand or by an AI assistant

[ispyisail]

QElectroTech can already run a JavaScript script on the open project
(Projet > Exécuter un script…). It asks for the file every time, though,
and a script can't be put on a button. The pull requests below add four
things.

1. Script buttons. Save a script in a scripts folder, next to your
own element collection, and it becomes a button with an icon. The button
shows up in Projet > Scripts, on a Scripts toolbar, in command search and in
the shortcut bar. The first lines of the file say what the button looks like:

// ==QETScript==
// @name     Add revision note
// @icon     note.svg
// @shortcut Ctrl+Alt+R
// ==/QETScript==
qet.addText(qet.currentFolio(), "Rev A", 40, 40);

One click is one undo step. Scripting stays off by default, as it is today.

2. A manager. Projet > Scripts > Gérer les scripts… lets you write, try,
give an icon to and delete scripts without using a text editor.

3. AI assistants, through the qet MCP server. The assistant reads the
list of calls, tries a script on a copy of a project, and stores it as a
button. It never presses the button: you do.

4. Live mode, off by default. An assistant acts on the project you have
open while you watch.

• With the setting on, every start shows a warning first.
• A script the assistant writes on the spot is shown to you before it runs.
• Every action is one undo step and is listed in an Assistant panel.
• An Arrêter button closes the connection.

5. A macro recorder. Projet > Scripts > Enregistrer une macro records
something you do by hand. When you stop, Copier la demande pour
l'assistant copies a request to paste into the assistant's chat. The
assistant reads the recording, writes a general script, checks that it
gives the same result as you did, and offers it as a button. PRs: #1227
(stacked on #1223) and #1228 (stacked on #1225).

Pull requests:

• Make a script run one undo step, and let it find the folio on screen #1219: undo and the new calls. It stands alone.
• Add script buttons: stored scripts with an icon in menu and toolbar #1220: the buttons. Add a script manager: write, try, give an icon to and delete scripts #1221: the manager.
• Add live mode: an AI assistant works on the open project as you watch #1222 and Add ask-first, an Assistant panel and safe commands to live mode #1223: live mode.

These five are stacked in that order. The MCP side is #1224 (script tools) and
#1225 (live tools).

Two questions. The PRs follow the answer in brackets unless someone
objects:

• Should scripts live only in your own folder, not inside .qet projects?
  A project received by email would otherwise carry code behind a button.
  (Only your own folder.)
• Does QElectroTech want live mode at all? It is Add live mode: an AI assistant works on the open project as you watch #1222, Add ask-first, an Assistant panel and safe commands to live mode #1223 and Add MCP live tools to act on the project open in QElectroTech #1225, and it
  can be dropped without touching the rest. (Keep it, off by default.)
