v0.2.0

Hercules 0.2.0 completes the Go-native renderer integration and the associated
correctness, performance, schema, security, and release-hygiene work.

Highlights

• Replaced the retired Python labours package with the in-repository Go
  renderer and added in-process hercules report generation.
• Added JSON rendering/export support, transactional report output, safer
  filenames, identity-private chart labels, and improved burndown, ownership,
  developer, coupling, Shotness, and temporal-activity visualizations.
• Added and corrected analysis capabilities including hotspot risk, onboarding,
  ownership snapshots/concentration, Kaplan-Meier code survival, temporal
  activity, and line-history replay.
• Added schema-2 validation and supported migrations, a checked-in protobuf
  schema snapshot, schema guardrails, and stricter YAML/PB error handling.
• Improved large-repository behavior with streaming burndown merges, sparse
  coupling matrices, managed remote caching, safer hibernation, and stronger
  lifecycle validation.
• Made the supported default build fully cgo-free and expanded CI coverage for
  cross-compilation, deterministic execution, races, fuzzing, visual regression,
  vulnerabilities, documented builds, and multi-architecture containers.

Migration notes

• The legacy Python renderer and Babelfish/UAST parser-service path are removed.
  Structural analyses now use tree-sitter; --dump-uast-changes is the
  tree-sitter-based replacement for the old dump workflow.
• Several analyses received semantic correctness fixes without wire-field
  changes. Recompute stored analysis data before comparing results across this
  release boundary.
• Readers now enforce explicit schema compatibility. See
  SCHEMAS.md
  and the
  schema changelog
  for the compatibility matrix and required user actions.
• Sentiment analysis remains experimental and requires the optional TensorFlow
  build tag; it is not included in default release builds.

Verification

The tagged commit passed the complete GitHub Actions suite, including unit,
race, fuzz, deterministic, end-to-end, schema, lint, visual-regression,
cross-compilation, vulnerability, documented-build, and container checks.
