Expose createInteractiveAiSession on route/loader PluginContext alongside the one-shot createAiSession. The prompt->parse->retry->pause->resume loop is reimplemented in an engine seam modeled on planning.ts (no engine await-input primitive exists). Reuses PlanningQuestion/PlanningResponse; stays generic with no plugin-specific concepts. Injected on route contexts only; tool/runtime contexts omit it (parity with createAiSession).

* Shared lazy accessor for `@fusion/engine`'s `createFnAgent`.
|
|

|
|
* Core can't import engine statically (engine depends on core, so a static
|
|
* import would create a cycle). Instead, engine wires its `createFnAgent` in
|
|
* via `setCreateFnAgent` when its module loads, and consumers in core read it
|
|
* back through `getFnAgent`.
|
|
*
|
|
* If engine never loads (e.g. tests that only import core), `getFnAgent`
|
|
* returns `undefined` and callers degrade gracefully.
