v0.4.0

Added

• Post-apply recommendation tracking (pro-monitor track): validates whether past recommendations were accurate by comparing post-apply Prometheus metrics against new resource requests. Classifies outcomes as SAFE, TIGHT, WRONG, or PENDING. Supports --format json for CI integration
• Cost impact estimation for requests-skew analysis: new --cost-cpu, --cost-memory, and --instance-type flags attach dollar estimates to resource waste. Includes per-workload, per-namespace, and cluster-wide cost summaries with built-in pricing for AWS, GCP, and Azure instance types
• Kustomize export format (--format kustomize): generates kustomization.yaml + strategic merge patch files for GitOps workflows
• Helm export format (--format helm): generates values.yaml fragment with resource overrides
• JSON version output (version --json): machine-readable build info for CI pipelines
• Commit hash and build timestamp in version output, matching project-wide convention

Fixed

• Wire ldflags version injection to CLI — version was hardcoded as a const and never read from build-time injection, causing brew-installed binaries to report stale version strings
• Reduce cyclomatic complexity across 10 functions and eliminate code duplication across 4 sites
• Resolve 433 lint warnings (errcheck, gocritic, revive, gocyclo, dupl) down to 1 pre-existing excluded warning
