kernel_chat v0.5.0

kernel_chat 0.5.0 evolves the conversational kernel while preserving present-first work and user-owned continuity.

• Separate selective project reentry from kernel/method retrieval through AGENTS.
• Regenerate methods from understood relations; circulate competence results and keep reusable learning with its causal owner.
• Provide a concrete optional cultivation path without a new registry or controller.
• Preserve configured local adapters by default; add independent --replace-adapter and no-write --preview-adapter.
• Clarify source publication, tagged distribution, installed host instructions and behavioral assimilation.

Validation: structural validator and all eight configuration tests passed on Windows and Linux for commit 924f650.
CI: https://github.com/GrazianoGuiducci/kernel_chat/actions/runs/34528283770

Upgrade: preserve fork state, competences and customizations; preview and reconcile the adapter before explicitly replacing it. Installing or updating account instructions remains a separate user-controlled action. This release establishes source validity, not host installation or later behavioral assimilation.

See INSTALL.md, CHANGELOG.md and docs/EVOLUTION_GUIDE.md for the operating paths, changes and accumulated reasons.
