[FEATURE] Have AgentReady list all the .gitignore entries it thought were missing for ".gitignore Completeness"

[wcohen]

Problem Statement

I am using AgentReady to attempt to make the performance co-pilot git repository a bit better for AI agents. When looking through the results I got a line saying:

Pattern coverage: 5/12 (42%)

Then further down it lists out some of them, but not all:

# Missing patterns:
.venv/
__pycache__/
.pytest_cache/
*.egg-info/
venv/

Proposed Solution

List all the missing patterns. Avoid having the developer search through and try to figure out which patterns remain.

Use Cases

Describe specific use cases where this feature would be valuable.

1. Developer can more directly use the list as a starting point

Acceptance Criteria

• Provides a list of all the missing .gitignore entries
