Version 0.2.1 — paste works, and fields fill their row

[timbogdanov]

What this changes

Two bugs reported from the Program sheet: an Anthropic API key could not be pasted into the key box, and the prompt field was too small. Neither turned out to be in that sheet.

Paste. electron/menu.js sets a custom application menu, which replaces macOS's default one wholesale — and on macOS the clipboard shortcuts inside web content are delivered by that menu. Its Edit menu had Undo, Redo, Select All, Deselect and Clear, and no Cut, Copy or Paste at all:

CLIPBOARD ROLES PRESENT: NONE

So Cmd+V had nowhere to go, in every text field in the app. Right-click offered nothing either, since Electron ships no context menu of its own and only the canvas had a custom one.

Each Edit item now does both halves: webContents[action]() for the text field (a no-op unless something editable has focus), then send(id) for the canvas, which the renderer drops while a field has focus. One key, whichever meaning the focus implies, and a menu item that still does what its accelerator does. Cut/Copy/Paste are new items; right-clicking an editable field now gets a menu built from the flags Chromium reports.

Two more from the same root:

• Cmd+Z in a text field undid a brush stroke instead of a typo.
• Clear was bound to a bare Delete. An unmodified key in the menu is swallowed application-wide, so Delete stopped deleting characters in every field — and fired alongside the renderer's own handler, clearing twice per press. The renderer owns it again; it already ignored text fields.

Field widths. .wide — the class meaning "fill the row" — was written input[type=number].wide. An attribute selector matches the attribute, so it skipped type="password" (the key field) and skipped an <input> written with no type at all (the prompt field). Measured in the running app:

field	before	after
API key	195px in a 491px row	353px
prompt	195px in a 491px row	412px

They missed the shared text-input rule for the same reason, which is why three fields carried duplicated inline styles — removed. And body{user-select:none} was inherited into every form field, so you could not select what you had just typed; inputs and textareas opt back in.

Verification

Drove the real window: put a key on the clipboard, focused #aiKey, fired the actual Paste menu item — the value lands, and the canvas is untouched by Undo/Select All while a field has focus. No renderer errors.

New regression checks in tools/verify-electron.py and tools/verify-ui.py, both of which fail on the code as it stood before this change. Full suite: 414 checks, 0 failures.

Checklist

• npm run verify passes
• Generated files re-run through their generator (stamps, codec fixtures) — none touched
• If it touches the desktop app, the browser build still works — the menu-owned key list and the Edit commands are both behind native(); the CSS fixes apply to both builds
• If it adds a stamp, the contact sheet was looked at — no stamps
