fix(stats): show max cyclomatic in the text complexity summary (#2384)

[carlos-alm]

Summary

The human-readable codegraph stats complexity line omitted maxCyclomatic, even though it's computed and present in stats -j. The line was internally inconsistent about which extreme it reports per metric: cognitive gets its max, MI gets its min, but cyclomatic only got its average — so a function at cyclomatic 40 was invisible in the default view while an equivalent cognitive outlier was shown.

Changes

• Added maxCyclomatic to the ComplexityInfo interface in src/presentation/queries-cli/overview.ts (the value was already computed by both the native and JS stats paths — this was purely a presentation-layer omission).
• printComplexity now prints max cyclomatic: N right after max cognitive: N, matching the JSON shape.

Verification

• lint: pass
• npx vitest run tests/presentation/queries-cli.test.ts: 31/31 pass (added a new stats test asserting both max cognitive and max cyclomatic appear in the rendered line)
• codegraph diff-impact --staged: 2 functions changed, 2 callers affected (stats() and its CLI execute wrapper — exactly the expected surface)
• Manually verified against this repo's own graph: Complexity: ... | max cognitive: 102 | max cyclomatic: 51 | avg MI: ...

Closes #2384

Greptile Summary

The PR adds the already-computed maximum cyclomatic complexity metric to the human-readable codegraph stats summary.

• Extends the presentation-layer complexity shape with maxCyclomatic.
• Prints maximum cyclomatic complexity alongside maximum cognitive complexity.
• Adds a focused CLI rendering test for both maximum metrics.

Confidence Score: 5/5

The PR appears safe to merge with no actionable correctness or security issues identified.

Both native and JavaScript stats paths always provide maximum cyclomatic complexity for nonempty complexity results, and the updated renderer is guarded against absent complexity data.

Important Files Changed

Filename	Overview
src/presentation/queries-cli/overview.ts	Adds the required metric field and renders it in the default complexity summary; all runtime producers supply the value.
tests/presentation/queries-cli.test.ts	Adds focused coverage confirming that maximum cognitive and cyclomatic values appear in text output.
