v0.1.1

Stabilization release for the initial harness workflow. This release strengthens
the theory, evaluation, failure-memory, and contributor guidance added around
the v0.1.0 early release.

Added

• Harness engineering theory document that separates repository harness health
  from observed agent effectiveness.
• Task outcome record template for comparable agent-work observations.
• Roadmap and expanded contributor guidance for profiles, drift checks,
  adoption examples, and release validation.
• Regression coverage that keeps the static site copy prompt aligned with the
  README adoption prompt.

Changed

• Compact root and generic AGENTS.md guidance while preserving command
  routing, analysis, validation, and commit rules.
• Clarify python3 validation commands for macOS/Linux environments where
  python is unavailable.
• Clarify Harness Doctor score scope and non-scored evaluation/governance
  signals.
• Strengthen adoption and update guidance around failure-memory records for
  user-visible runtime failures, high-risk bug paths, failed checks, repeated
  agent mistakes, and cross-environment mismatches.
