CI/CD Pipeline Modernization

Break down CI/CD pipeline modernization into incremental phases:

Current Pipeline State:
{{current_pipeline}}

Pain Points:
{{pain_points}}

Target State:
{{target_capabilities}}

Decompose into improvement phases:

1. FOUNDATION PHASE
   Subtask 1.1: Pipeline as Code migration
   Subtask 1.2: Secret management setup
   Subtask 1.3: Artifact versioning standardization

2. TESTING ACCELERATION
   Subtask 2.1: Test parallelization
   Subtask 2.2: Test result caching
   Subtask 2.3: Flaky test quarantine

3. DEPLOYMENT AUTOMATION
   Subtask 3.1: Environment provisioning automation
   Subtask 3.2: Deployment strategy implementation
   Subtask 3.3: Rollback automation

4. OBSERVABILITY INTEGRATION
   Subtask 4.1: Build metrics collection
   Subtask 4.2: Deployment tracking
   Subtask 4.3: Failure alerting

For each subtask specify:
- Implementation approach
- Dependencies on other subtasks
- Success metrics
- Time estimate
- Risk mitigation
