Typed END, MID, CEN, GCEN, NOD, QUA, INT, APP, EXT, INS, PER, TAN, NEA,
PAR (any start of the word from three letters, with `_`/`'` prefixes)
and NON push a one-pick snap frame on the point-modifier layer: the
prompt reads "Endpoint of:", a typed point is snapped with that mode
alone within the aperture (or rejected with "No Endpoint found for
specified point."), and the canvas snaps the cursor with it
(Session::snap_override). A command's own keyword still wins (ARC/ZOOM
`cen`); `_cen` always snaps. Overrides nest with FROM and the filters.
Shift+right-click or Ctrl+right-click on the canvas opens the object
snap menu (From, Mid Between 2 Points, Point Filters, the snap modes,
None, Osnap Settings...), whose items type the same overrides. Tab over
a snap marker with nothing typed cycles the candidate snaps
(pointmod::snap_candidates: the running snap first, then the closest of
each mode).

A point modifier typed at any point prompt pushes a frame on the session
(Session::point_mods) that asks for what it needs ("Base point:",
"<Offset>:", "First point of mid:", ".X of", "(need YZ):") and hands one
point to the command, so every command gets them from the command line
and in scripts, and they nest (FROM then M2P). `*x,y`, `*@` and `@*`
parse as world coordinates (the same as the plain forms: no UCS yet).
`<a` locks the next point to that angle from the base point: a typed
distance follows it, a pick is projected onto it, typed coordinates win.
TK is left to object snap tracking (#379).
