The compiler had every phase and the PRG/MAP writer but no program on the
C128 that used them, so this adds the prompt, the planned code base, the
three container sections and the one-screen summary, plus a verifier that
drives the launcher through success, syntax failure and output collision
and runs the generated PRG.

E06-S06 routes deletion through a fat reference to obj_delete behind the heap's
always-on validation, so a stale value is refused with IF_ERR_FREED instead of
reading a freed destructor, and adds the objects.n8 parser fixture.

E07-S02 shares one launcher implementation that locks the writable image and
waits for the emulator exit and image flush, with x64sc for the editor and x128
for the compiler.
