Add test for buildSystemPrompt with non-empty style profile

[404-Page-Found]

Description

The existing test in \ ests/build-system-prompt.test.mjs\ only tests \�uildSystemPrompt\ with an empty profile (totalCommits = 0). The \�uildStyleGuidance\ function has many conditional branches that are never tested:

• Imperative mood guidance
• Sentence case guidance
• Common prefix guidance with rate >= 30%
• Multiple prefix listing
• Scope usage guidance
• Body usage guidance

Proposed Solution

Add a new test that provides a profile with non-zero values for all these fields and asserts the prompt includes the expected guidance strings.

Why It's a Good First Issue

The file already exists with one test. Adding a second test case with a populated profile exercises the main logic of the style guidance builder. Pure function, no I/O, clear expected outputs.
