Selecting an INSERT with attributes now adds an editable "Attributes" section to the Properties panel — each tag is a row whose value can be changed inline (Enter commits, undo works, the attribute text repaints). Previously attribute values could only be reached through ATTEDIT, which didn't let them be changed (#192). Attribute tags are runtime strings, so they can't ride the geometry edit path whose field key is `&'static str`; a dedicated PropValue:: AttrText variant plus PropAttrInput/PropAttrCommit messages carry the tag. Values are stored verbatim (no expression evaluation, since attribute text is free-form). Also guard the panel's in-progress edit buffer: it now only carries across a rebuild when the selection is unchanged (a commit-triggered refresh), so a typed-but-uncommitted value can't display or commit onto a different entity — e.g. two title blocks sharing a REV1 tag. This closes a latent stale-buffer leak that affected geometry fields too. Co-Authored-By: Claude Opus 4.8 <[email protected]>
