feat: add Test Coverage Optimizer recipe (#5118)

[shiv669]

Summary

Intermediate recipe for Issue #5118 that creates a Test Coverage Optimizer using Developer + Memory extensions.

Recipe Features

• Extensions: Memory (loads/stores patterns) + Developer (analyzes code/generates tests)
• Integration: Sequential chaining - Memory retrieves learned patterns → Developer uses them for analysis → Memory stores results
• Parameters: 5 configurable inputs (project_path, test_framework, coverage_threshold, focus_areas, generate_templates)
• Activities: 7 clear user-facing steps
• Use Case: Analyzes existing tests, identifies coverage gaps, generates targeted test suggestions

We had another test coverage recipe submitted I think from ARYPROGRAMMER where I had also commented that storing test coverage results in the Memory extension was not a great utilization, as those patterns and data would be sent to the LLM for every other kind of request the user would make of goose, even if the request wasn't about testing or coverage etc, so I'd love to see this recipe updated to store that data in a separate file and have the recipe read/write that file instead.
