A file's saved selections are untrusted: on load at most 25 are kept, names
are trimmed, capped at 255 characters and unique, and ids the document
doesn't have are dropped (after fix_next_id such an id would select whatever
object is drawn next). Save and Edit Selection cap names the same way. The
limit, the name cleanup and the default "Selection N" live on
SavedSelection, shared by the engine, the Save Selection dialog and the
Select menu's slot table. docs/mcp.md documents the select.save /
savedList / recall / editSaved commands; ROADMAP counts 13 stubbed menu items
and names what's still missing (Update Selection, the Layers panel menu).

Save Selection… asks for a name and keeps the selection in the document (saved with
the file, undoable, at most 25) instead of in session memory keyed by the title.
Each saved selection is listed at the bottom of the Select menu and a click selects
its objects again. Edit Selection… opens a dialog with the list to rename or delete
them, applied together on OK as one undo step (select.editSaved takes `edits`).
The menu stub count in the ROADMAP goes from 16 to 15.
