Q backed out of a build mode or toggled deconstruct mode; it now clears the
selection as its middle case. That needed a rule for a selection held while a
build mode is active, a state the code allows today: clearAll() is called only
by a click or drag that hit nothing, so a selection survives into builder,
blueprint, and deconstruct mode.
Make the two mutually exclusive instead, matching what the controls panel
already shows: entering any build mode clears the selection. The blueprint
gestures read the selection before the mode entry clears it, so C and Ctrl+C
lose nothing.
Drops the accuracy carve-out that had C / Ctrl+C merely omitted from the build
contexts on the strength of a surviving selection -- with no selection there,
they are unavailable rather than omitted, and the list is the three cases its
intro claims.
Requirements only; no code yet.
