[task] Fix SC2215 flag-as-command issues in blog-auditor and unbloat-docs

[github-actions]

Objective

Review and fix command syntax issues in blog-auditor and unbloat-docs workflows that are triggering SC2215 warnings.

Context

Static analysis identified 2 SC2215 warnings ("This flag is used as a command name. Bad line break or missing [ .. ]?") which may indicate formatting problems or incorrect shell syntax.

Related to discussion #3527.

Approach

1. Review the workflow files for blog-auditor and unbloat-docs
2. Identify lines where flags appear as command names
3. Check for:
   • Missing command before flags
   • Incorrect line breaks in multi-line commands
   • Missing test brackets [ ] in conditional statements
4. Fix syntax issues while preserving functionality

Files to Modify

• .github/workflows/blog-auditor.md
• .github/workflows/unbloat-docs.md

Acceptance Criteria

• Command syntax corrected in both workflows
• Run gh aw compile blog-auditor --actionlint shows no SC2215 warnings
• Run gh aw compile unbloat-docs --actionlint shows no SC2215 warnings
• Workflows compile successfully
• Test workflows to ensure functionality unchanged

Impact

Eliminates 2 potential syntax errors and improves workflow reliability.
