Cryptext x64 0.11t compile fix1
================================

FASM 1.73.35 reported:

  Cryptext64.asm [171]:
      js .cng_failed
  error: undefined symbol 'start.cng_failed'.

Cause:
The new CT_LANG_PTR macro used `local done`. In FASM macro expansion that
introduced a generated non-local symbol into the surrounding source stream,
which changed the base used by existing dot-local labels. Thus the later
`.cng_failed` no longer resolved as `start.cng_failed` from the earlier jump.

Fix:
CT_LANG_PTR now uses the anonymous FASM label pair `@f` / `@@:`. Anonymous
labels do not become the base for the caller's dot-local labels.

No runtime logic, crypto, vault format, CT64FILE V1, file transaction or UI
geometry was changed by this compile fix.

Build/runtime verification remains to be performed with the user's FASM
1.73.35 Windows environment.
