v0.26.0 — Design hardening and CQRS bus parity

🌴 Palm Engine 0.26.0 — Design hardening and CQRS bus parity

Summary

Palm 0.26.0 is a quality release on top of 0.25.0. It hardens the Design Service, fixes in-process MCP for design impact/commit, and introduces a registry-driven CQRS transport model for service domains. No breaking API changes — upgrade from 0.25.0 is drop-in.

Highlights

• In-process MCP fixed — palm_design_impact and palm_design_commit work on standalone ServerContext (no missing AnalyzeDefinitionImpactQuery handler).
• Service CQRS contributors — definitions and design register transport via ServiceCqrsContributor; single collect_cqrs_catalog() for host and standalone (ADR-009).
• Registry-driven design dispatch — DesignService.dispatch uses design_commands() + handler table instead of an if-chain.
• Design CQRS bindings — bus-level transport for propose/validate/impact/commit (business rules stay in DesignService).
• Correctness hardening — commit re-runs impact before auto-migrate; durable proposal index cleanup; pipeline + wizard design contributors.
• Dogfooding — design_proposal_demo.py end-to-end with auto-migrate.

For agents: Restart palm-mcp after upgrade. Verify with palm_design_propose_flow → palm_design_impact → palm_design_commit.
