A profile traced over a face sketch's projected boundary left the extrude's caps and sides without an exact planar source, so a sketch or offset plane on the new top face was refused. The drawn curve is now the edge's source where it covers a projection. Clearer fixed-plane message; regression tests in the engine, UI harness and design corpus, plus a corpus-wide flat-face attachment check (known gaps under #491-#495).

* fix: name an untitled design after its file on save and open
Design tabs all read "Untitled" because a design's name only ever came
from file.new. Saving a design still under the default name now names it
after the file (bracket.solidcraft -> "bracket"), and opening a file whose
stored name is the default shows its file name. Names chosen by the user
are kept. The rename is part of the save, so it is not an undo step and
does not leave the design marked as changed.
