style: apply ruff 0.15.2 formatting to drifted files (unblocks CI format check)

[wernerkasselman-au]

What this fixes

The CI ruff format --check src/ tests/ job is currently failing on main, not on any one PR. Four files were committed under an older ruff and no longer match ruff format under the version this repo now pins (ruff>=0.15.0 in pyproject.toml, which uv.lock resolves to 0.15.2), so the format job reports them as needing reformatting and exits non-zero. Because that check runs over the whole tree, every open PR inherits the red job regardless of what it changes. I hit it while getting CI green on two unrelated fixes (#204, #205), and it traces back to main itself.

The change

uv run ruff format src/ tests/, nothing more. It touches exactly the four drifted files and leaves the other 120 untouched:

• src/skillspector/nodes/analyzers/static_runner.py (a hand-condensed frozenset({...}) literal that 0.15.2 expands one element per line)
• tests/nodes/analyzers/test_binary_and_pe3_filtering.py
• tests/nodes/analyzers/test_mp2_regex_backtracking.py
• tests/nodes/test_llm_analyzer_base.py

No behaviour change: ruff format only adjusts whitespace and literal layout. I kept it to formatting on purpose so it is a safe, reviewable catch-up rather than mixing in anything else.

Verification

uv run ruff format --check src/ tests/   # 124 files already formatted (was: 4 would reformat)
uv run ruff check src/ tests/            # All checks passed
uv run pytest tests/nodes/analyzers/test_binary_and_pe3_filtering.py \
              tests/nodes/analyzers/test_mp2_regex_backtracking.py \
              tests/nodes/test_llm_analyzer_base.py -q   # 147 passed

If you would rather pin ruff to an exact version (so a future ruff bump does not re-introduce this drift on a >= floor), I am happy to follow up with that separately; this PR just restores the clean check against the version already in the lock.

Approving — formatting-only (ruff 0.15.2). I diffed the content: _BINARY_EXTENSIONS membership is unchanged (only reflowed one-per-line), and the signature/log/test reflows carry no logic changes. Unblocks the CI format check.

@wernerkasselman-au fix the CI issue

[wernerkasselman-au]

Closing as obsolete. The ruff 0.15.2 formatting this PR applied is already present on main, and uv run ruff format --check src/ tests/ passes cleanly there (144 files formatted), so the CI format check is already green on main.

This branch is based on an older main (7bc9c0f), and its head predates newer commits to src/skillspector/nodes/analyzers/static_runner.py and tests/nodes/test_llm_analyzer_base.py (69ac3ba, 1c796a5). Merging it as-is would revert those changes. Rebasing onto current main drops the only commit ("patch contents already upstream"), leaving nothing to merge.

No action needed; the formatting goal is achieved on main.
