Fusion 8cdc0ff449 feat(FN-3155): add createAiSession plugin context API with DI wiring
This merge brings FN-3155's plugin `createAiSession` API (types, DI hooks, engine adapter, context wiring, docs, and tests), FN-3056's task title sanitization, and FN-3129's tokenized footer and mobile initialization for MissionManager. It also adds CentralCore Docker node management, a new AddNodeM

/**
* 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.
