[Code Quality] Refactor top 50 complex functions to reverse growing complexity trend

[github-actions]

Description

The Daily Sentrux report for 2026-07-20 shows 1,045 functions exceeding complexity thresholds, up from 988 two weeks ago (+57 in ~2 weeks). The codebase quality signal has slowly declined from 5239 to 5221 over 30 days, with complexity as the primary bottleneck.

The recommended action is to target the top 50 highest-complexity functions for refactoring, which could meaningfully move the quality signal from ~5221 toward 5500+.

Suggested Changes

1. Run sentrux or equivalent to list all 1,045 complex functions sorted by complexity score
2. Select the top 50 by complexity (highest score first)
3. For each: split into smaller focused functions (≤20 lines each where possible), extract helpers, reduce nesting
4. Validate: each refactored function should pass make test and reduce complexity below the threshold
5. Target files are concentrated in pkg/workflow/ and pkg/cli/ based on prior lint reports

Files Affected

• Concentrated in pkg/workflow/ and pkg/cli/ (based on prior analysis)
• Run make golint-custom to identify specific files

Success Criteria

• Net reduction of ≥50 complex functions (from 1,045 toward 995)
• Sentrux quality signal improves from 5221 toward 5300+
• All existing tests pass
• No functions introduced above the complexity threshold

Priority

Medium — trend is worsening slowly; proactive refactoring now is cheaper than later
