Broken ref: brief-template.md referenced with wrong path depth

[arcaven]

Found by

File reference validator (PR #8)

Description

2 files reference ../../templates/brief-template.md which resolves to workflows/templates/ (doesn't exist). The actual file is at workflows/module/templates/brief-template.md.

Affected files

File	Line	Current ref
src/workflows/module/steps-b/step-13-review.md	6	../../templates/brief-template.md
src/workflows/module/steps-b/step-14-finalize.md	5	../../templates/brief-template.md

Proposed fix

Change ../../templates/brief-template.md → ../templates/brief-template.md in both files.

Confidence: VERY HIGH — target file verified at src/workflows/module/templates/brief-template.md.
