Summary

• add a real Git regression test for untracked binary files in workspace diff
• verify binary additions are reported as added/binary with no line counts
• verify the real Git index remains unmodified after result diff generation

📝 Walkthrough

Walkthrough

This PR adds a single test function to validate that the workspace diff provider correctly identifies untracked binary files as added with the binary flag set and appropriate diff metadata, while verifying the underlying git status output.

Changes

Untracked Binary File Diff Test

Layer / File(s)	Summary
Untracked binary file diff handling test coding-agent/tests/coding_agent/environment/test_docker_workspace_provider.py	Test initializes a git repository with an untracked binary file (new.bin) and asserts that workspace_diff_from_config reports it as added with binary=True, zero addition/deletion counts, no file-level addition/deletion values, and verifies git status --porcelain=v1 output shows ?? new.bin.

Possibly related PRs

• delete-cloud/Coding-Agent-Loop#146: Implements git workspace diff detection that this test validates, particularly the handling of untracked binary files as added files.
• delete-cloud/Coding-Agent-Loop#153: Also extends the same test file with untracked file diff/patch validation, complementing this binary-specific test case.

Poem

🐰 A binary bounces into sight,
Git marks it with a "??" bright,
The test checks status, flags, and form—
Untracked files now norm! 📝✨
