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.

Nova128 is an object-oriented language with an on-machine C128 compiler.
This adds the spec, decisions, architecture, backlog, and story claims,
plus the grammar fixtures (E00-S02), disk-image builder (E07-S01), and
the x128-verified platform probes:

- E01-S01 minimal native PRG
- E01-S02 MMU/common-RAM probe. With bottom common on, a P0/P1 pointer
  aimed at bank 1 lands in bank 0 at the translated page. The verifier
  traces every MMU write in the probe window.
- E01-S03 KERNAL wrapper (kcall). CHROUT, drive status, and a
  device-not-present failure work from bank 0 and bank 1 mappings.
  A/X/Y/C/ST are preserved and the MMU state is restored exactly.
- E01-S04 40/80-column display and clock probe
