* support symbolic shapes in split/chunk when split dim is concrete
Previously split() and chunk() required all dimensions to be concrete.
Now they only require the dimension being split to be concrete, allowing
them to work with tensors that have symbolic shapes in other dimensions.

* fix dim resolution order in split/chunk
Ensure dim_sz is retrieved after dim is resolved, not before.
The previous one-liner evaluated self.shape[dim] with the original
unresolved dim value.

* qwen model is mostly working
* add Q4_K quantization support to GGUF parser, add qwen3:1.7b model
- Add Q4_K (type 12) dequantization in nn/state.py
- Add qwen3:1.7b model using Q4_K_M quantization (smaller than Q8_0)
- Make bos_token_id optional for models like Qwen3 that don't have it
- Fix line length issues and add preset parameter to SimpleTokenizer

* schedule: cache unbinds for consistent cache keys
strip BIND values before computing cache key so different bound values
(e.g. KV cache positions) hit the same schedule cache entry.

* schedule: cache unbinds for consistent cache keys
different bound variable values (e.g. kv cache positions) now produce
the same schedule cache key by unbinding BIND(DEFINE_VAR, CONST) before
computing the cache key and rebinding after lookup.

* schedule: cache unbinds for consistent cache keys
When scheduling, BIND(DEFINE_VAR, CONST) nodes are now unbound to
tagged DEFINE_VARs before computing the cache key. This ensures that
the same computation with different bound values (e.g., different
KV cache positions in LLM) gets the same cache key and reuses the
cached schedule.
The fix:
- pm_pre_sched_cache: replaces BIND with tagged DEFINE_VAR
- pm_post_sched_cache: restores tagged DEFINE_VAR back to original BIND
- pm_remove_rangeify_tags: excludes DEFINE_VAR to preserve tags through rangeify
- var_vals extracted from BINDs before cache key computation
