feat: add universal @test-fix-agent invocation template

Enhancement:
- Add dynamic prompt template for @test-fix-agent
- Supports 3 task types: test-gen, test-fix, test-fix-iteration
- Auto-adapts based on task.meta.type via configuration maps

Template Features:
- taskTypeObjective: Task-specific goals
- taskTypeSpecificReads: Required file reads per type
- taskTypeGuidance: Execution instructions per type
- taskTypeDeliverables: Expected outputs per type
- taskTypeSuccessCriteria: Completion validation per type

Benefits:
- Orchestrator uses single template for all task types
- Claude dynamically fills in type-specific details
- Reduces duplication, maintains consistency
- Clear guidance for criticality assessment (high/medium/low)
- Progressive testing integration (affected_only vs full_suite)
