/p command reads unnecessary scripts - should analyze Makefile only

Issue

The /p (push/PR) command reads many unnecessary script files when detecting project commands.

Current Behavior

• Reads setup_auth.sh, bastion.sh, port_forward_db.sh, sync_*.sh, etc.
• Takes time and resources to analyze irrelevant files

Expected Behavior

• Should primarily analyze Makefile for make test, make lint definitions
• Only read additional scripts if Makefile references them directly
• More efficient command detection

Example

For make test analysis:

1. ✅ Check Makefile test target
2. ❌ Don't read unrelated setup/deployment scripts

This would make command detection faster and more focused.
