- New Advanced controls on the import page: O(1) attention spec (off / all /
deep N / explicit layer list) plus the --o1-m / --o1-window / --o1-sink knobs
with validated defaults (32 / 128 / 4) and explanatory hints.
- Backend passes --o1* to the native `cortiq convert`; fails fast with clear
messages when combined with Python-only options, used on GGUF imports, or
when the installed cortiq predates 0.2.0 (the hint needs the new runtime).
- The hint is recorded in the .cmf header (weights byte-identical); the runtime
applies it at load. Verified end-to-end: converted a model with --o1 all and
the runtime logged "o1 nystrom attention: 2/2 layer(s)".
