feat: multi-source model discovery (HF default, legacy cache, LM Studio) (#4591)
* feat: multi-source model discovery (HF default, legacy cache, LM Studio)

* Fix multi-source model discovery bugs

- Fix lmstudio_model_dirs: add ~/.lmstudio/models as default path,
  remove dead sys.platform branch, add dedup via seen set
- Fix _setup_cache_env: preserve legacy HF cache env vars when the
  legacy hub directory exists and is non-empty
- Fix _scan_lmstudio_dir: use absolute path for id field so
  is_local_path() returns True
- Remove LM Studio dirs from allowed_roots (scanned unconditionally)
- Replace bare except passes with logger.warning in legacy cache blocks
- Fix delete_cached_model to search both default and legacy HF caches
- Make lmstudio_dirs non-optional in TS interface (matches Python schema)
- Exclude lmstudio source from trainable model filter
- Remove unused import sys

* Scan HF default cache alongside legacy and active caches

When _setup_cache_env overrides HF_HUB_CACHE to the legacy Unsloth
path, the standard HF default cache (~/.cache/huggingface/hub) was
never scanned, hiding models downloaded before Unsloth Studio was
installed.

Add hf_default_cache_dir() and _all_hf_cache_scans() helper that
deduplicates and scans all three HF cache locations (active, legacy,
default). Used in list_local_models, list_cached_gguf,
list_cached_models, and delete_cached_model.

* [pre-commit.ci] auto fixes from pre-commit.com hooks
