 		Reduce and tighten code comments and docstrings repo-wide (#6095) 
Trim and tighten code comments and docstrings across the repository. Comment-only: every changed file verified code-identical to main via AST/token comparison.

 		Formatting: ruff line-length 100, kwarg-spacing passes, drop blank after short local imports (#6079) 
Raise ruff line-length to 100 and extend the local pre-commit format pipeline (def-signature magic-comma normalization, short multi-line assert collapse, kwarg '=' spacing, blank-line-after-short-import removal, adjacent string-literal / f-string+plain merge, redundant-pass pruning). Every transform re-checks the file AST and is dropped if it would differ; the whole-repo reformat is verified AST-identical per file and idempotent.

336bec216a Refactor Ollama template wiring and harden packing helpers (#3890) 
* Refactor Ollama template wiring and harden packing helpers

Signed-off-by: Mohammad Miadh Angkad <MAngkad.BSDSBA2027@aim.edu>

* Fix Qwen3 and Gemma3n template bindings and tidy packing test helper

* Fix gptoss Ollama comment and tinyllama stop parameter

- Fix wrong comment referencing gemma3n for gptoss_ollama in chat_templates.py
- Add missing stop keyword to tinyllama PARAMETER in ollama_template_mappers.py

* Fix _DummyTrainer compatibility across TRL versions

The try/except only handled the removal of return_position_ids
(TRL v0.24+) but not the absence of padding_free (TRL v0.18.2).
Gracefully degrade through all optional collator flags so the
test works from trl>=0.18.2 through v0.27+.

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