v0.10.0-beta.1

Added

• #15 — Undo/redo: Ctrl/Cmd+Z undoes your last edit and Ctrl/Cmd+Shift+Z (or Ctrl+Y) redoes it, also available as buttons in the header. History is kept for the floor you're on and for the Property tab, and a drag or slider movement counts as one step. Reset floor/property can be undone too. While tracing a room, wall or scale line, Ctrl/Cmd+Z still removes just the last point.
• Move a whole room — select a room, then drag inside it to move it together with its label and the devices placed in it.
• Debug logging (Settings, off by default) — records what the panel does (loads, saves, errors, mesh loads) to spatial_context_debug.log in your config folder, and More options → Download debug report produces a single file to attach to an issue. Both contain IDs and counts only, never device names or positions.
• Update checks — after an update, the panel tells you if Home Assistant still needs a restart, or if your browser is running an older copy of the panel and needs a reload.

Changed

• The panel is now always re-checked for updates when the page loads, so updates no longer get stuck behind a cached copy in the browser (Safari especially).

Fixed

• A failed save now shows a banner with the reason and a Retry button, instead of failing silently.
• A checkbox, slider or dropdown that kept focus after being clicked no longer blocks keyboard shortcuts such as Delete and Ctrl/Cmd+Z.

⚠️ Restart Home Assistant after updating.
