Path injection (#22, #28, #29, #30):
- Switch from Path.relative_to() to os.path.realpath() + str.startswith()
in all four path-validation sites across finetune and rl UI data_loader.py
and finetune app.py. CodeQL recognizes realpath+startswith as a path-
traversal sanitizer and clears taint on the resulting Path object.
- Also simplify finetune/app.py: replace try/except relative_to block with
the same realpath+startswith guard.
Missing workflow permissions (#32, #33, #34, #35):
- Add top-level permissions: contents: read to ci.yml, docs.yml, lint.yml,
and security.yml. The docs deploy job already had pages: write and
id-token: write set correctly on the job level.
