Same style fix applied to the README earlier, extended everywhere:
replaced " -- " with commas/colons/periods (picking whichever reads
right per occurrence, splitting into two sentences where the clauses
were independent), fixed a few user-facing strings along the way
(entity list rows, placement/strike toasts, ambiguous-candidate tag,
shell picker button label). Left three intentional non-prose uses
alone: the "unassigned" dash glyph in firing_panel.py (and its
docstring diagram), and ocr.py's dash-variant regex character class,
which needs to literally match em/en-dashes in OCR'd text.
Also caught and fixed a stale models.py docstring claiming "no solver
yet" (solver.py has existed for a while) while touching that
paragraph anyway, and a formatting artifact in coord_dialog.py's
docstring left by the sed pass (misaligned comma from a since-removed
alignment gap).
Verified: py_compile across all files, the 9-screenshot OCR
regression sweep, and a GTK smoke test exercising the edited
toast/placement code paths.
