release: bump version 8.5.1 → 8.6.0 (Dialogic Chronos)

[nullhack]

Release 8.6.0 — Dialogic Chronos

Terminology Standardisation

• walkthrough replaces standalone 'scenario' in simulation context
• Rule block replaces 'story'/'user story'
• Example block replaces 'BDD scenario'/'BDD example'
• behavior hint replaces 'scenario hint'/'Scenarios:'
• Drop As a/I want/So that user story format from Rule blocks

Spec Architecture Restructured

• Behavioral rules now single-source in .feature files
• domain_spec.md structural only; behavioral sections as derived summaries
• Simulation writes Rule blocks directly to .feature during spec-validation
• Planning refines: discovery → breakdown → examples

Technology Requirements Chain (DSPy post-mortem fix)

• domain_spec.md Technology Requirements table
• simulate-spec writes tech constraints to .feature
• review-gate verifies constraints against implementation
• accept-feature traces technology Q&As

Other

• Title convention 3–8 → 2–6 words, with explicit verification in 6 skills
• Gherkin knowledge gaps closed in simulate-spec, discover-features, break-down-feature
• Consolidated duplicate discover-rules skill
• All 6 flows validate clean
