Stage 2 of #429. Until now an agent could only look at the editor.
Now it reads the project and changes it through the same commands
the user's own edits run, so every change shows up live and one
Ctrl+Z takes back a whole agent call.
- Read tools: list_assets, get_asset, get_graph and catalog. The
catalog lists the commands with their arguments, the nodes of a
graph from the same palette the user sees, asset types and
variable kinds.
- run_commands runs its steps as one undo step named "Agent: ...".
A failing step rolls back the steps before it. The answer names
the step and the reason the editor gave.
- A step can name what it made ("as") and later steps use "$name".
Each step is built after the one before has run, so one call can
make a behavior and fill it.
- 23 commands cover assets, variables, scene objects and graphs.
Textures, fonts, sounds and videos need a file and are left out.
- open, select, play and undo/redo drive the editor.
- Deleting asks the user with the same text as their own delete.
The tab sends "wait", and the relay then gives the call 2 minutes
instead of 30 seconds.
- tools.json is the only source of the argument schemas. argCheck
checks every call against them before anything runs.
- An open menu now names its first entries in get_view, instead of
an empty title.
- The new host functions live in editorToolHost.ts, so Editor.ts
does not grow further.
Found while testing: e2e 71 hung for 30 s in Page.navigate after a
failure. The beforeunload guard of an unsaved project held the page
and hid the real error. The module now reports the error first and
waits for the save before it navigates.
Tests:
- Gate on melektaus-atx: CHECK EXIT 0, 317 files, 4903 tests.
- agent-edit 14/14, agent-view 10/10, relay 24/24.
- e2e 71 16/16 on atx and against the live site. One call builds a
sprite with an arrow-key behavior, play moves it from x 0 to -125,
and one undo restores the assets exactly.
- Counter-checks turned red: no rollback, a partial undo, no delete
question, a relay that ignores "wait".
