Release v0.5.1

This is a patch release to fix the following problem and root cause:

Problem

Copilot CLI running inside AWF container had ~2x larger system prompt (522KB vs 275KB), with instructions being
loaded twice.

Root Cause

Git's "safe directory" security feature rejected the bind-mounted repository directory because:

• Container runs as root (UID 0)
• Mounted directory owned by host user (UID 1000)
• Git refuses to operate on directories with mismatched ownership

Impact

When git root detection failed, Copilot CLI fell back to scanning for .github/instructions/ from multiple
starting points (both CWD and HOME), finding the same directory twice since CWD is nested inside HOME.

Fix

Added to containers/agent/entrypoint.sh:
git config --global --add safe.directory '*'
