## Why #29856 already owns the durable thread intent and exact environment binding. This PR adds only the small missing extension boundary: an extension can contribute one named World State section, while core still owns persistence, diffing, and model-visible fragment types. This lets skills stay in the skills extension instead of moving their runtime into core. ## Shape ```text extension-owned state | | contribute section id + JSON snapshot + renderer v core World State | | compare with the previous snapshot v no message, or one incremental model-visible update ``` The extension API is deliberately small: ```rust fn contribute_world_state(...) -> Vec<WorldStateSectionContribution> ``` Core adapts the rendered result to `ContextualUserFragment`, records the snapshot, and keeps the existing compaction/resume behavior. ## What changes - Adds extension-owned World State section contributions. - Calls those contributors from the existing per-step World State builder. - Restores durable selected capability roots into extension thread state on resume. - Keeps the actual model-context fragment and rollout machinery in core. ## What does not change - No skill or MCP implementation moves out of its extension. - No new file watcher, generation, or RPC. - No generic migration of existing World State sections. - No change to the stable environment-ID assumption from #29856. ## Example ```text step 1 snapshot: skills = [] step 2 snapshot: skills = [executor-demo:deploy] core asks the skills extension to render only that change. ``` ## Stack 1. **This PR:** let extensions contribute World State sections. 2. Project executor skills through the skills extension. 3. Pin one MCP runtime to each model step. 4. Project selected MCP/app/connector metadata by environment availability. 5. One end-to-end integration scenario.
