v0.3.5 — Selection-only canvas

The canvas now leaves editing instructions, progress and results in the current Codex chat. Its existing footer shows only the selected count and names, with no extra selection row, prompt box or submission button.

Selection context still syncs silently to capable hosts. Codex verifies the current targets through canvas_selection, limits edits to their subtrees, and checks the preview and saved design. The obsolete canvas_prepare_edit and canvas_edit_status tools have been removed; the plugin exposes 184 tools.

Validation: package checks, 59 regression tests, skill validation, isolated native selection and bridge smoke tests, actual browser single/multiple selection, narrow light layout, live dark-theme switch, Save and independent reopen all passed. The local installed plugin also passed the bundled Codex host check. Live embedded Codex UI presentation remains unverified; the public runtime catalog is unchanged.

Reconnect the plugin and reopen the canvas to load the new UI. See validation details.
