v0.12.0: user-owned flows and model adapters

[KodingDev]

Summary

• replace automatic workflow routing and the forced output style with a model-independent professional engineering standard
• make formal flows explicitly user-invoked across Claude Code, Cursor, Copilot, and Codex
• add atomic model adapters with Opus 4.8, Sol, Fable, fallback, and override profile resolution
• simplify model-owned disciplines and make verification and review effort risk-proportionate
• release the redesign as 0.12.0

User impact

Ordinary requests remain ordinary agent work. Formal brainstorm, sketch, execute, review, commit, document, and auto flows run only when directly invoked. debug, research, triangulate, delegate, and respond remain available as narrow internal disciplines.

Session start now injects the shared professional standard plus only the adapters selected for the active model profile. Unknown models receive the baseline rather than a guessed profile. Project and customer policy remains in repository instructions.

Validation

• corepack pnpm run check — formatting, lint, typecheck, and 37 tests passed
• claude plugin validate . — passed
• git diff --check — passed
• Codex SessionStart fallback smoke test — baseline plus all four Sol adapters emitted

The paid live promptfoo corpus was not run; it remains an on-demand, non-blocking evaluation.
