Trim and tighten code comments and docstrings across the repository. Comment-only: every changed file verified code-identical to main via AST/token comparison.
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.
* Rename cli/ to unsloth_cli/ to fix namespace collision with stringzilla
stringzilla installs a namespace package at cli/ (cli/split.py, cli/wc.py)
in site-packages without an __init__.py. When unsloth is installed as an
editable package (pip install -e .), the entry point script does
`from cli import app` which finds stringzilla's namespace cli/ first and
fails with `ImportError: cannot import name 'app' from 'cli'`.
Non-editable installs happened to work because unsloth's cli/__init__.py
overwrites the namespace directory, but this is fragile and breaks if
stringzilla is installed after unsloth.
Renaming to unsloth_cli/ avoids the collision entirely and fixes both
editable and non-editable install paths.
* [pre-commit.ci] auto fixes from pre-commit.com hooks

* Update stale cli/ references in comments and license files
