refactor(runtime): own local movement and outbound cadence

Move the canonical local movement controller, body/motion managers, object clock, movement wire data, and MTS/jump/AP sender into AcDream.Runtime. Replace process skill defaults with typed Runtime character options, make graphical and direct commands borrow one autorun owner, retain the construction-time PartArray seam, and include movement in terminal ownership convergence.

Preserve the accepted pre-inbound movement/jump and post-inbound autonomous-position order while moving the exact packet/cadence fixtures into Runtime tests. Add graphical/direct parity, two-instance isolation, teardown, allocation, architecture, and divergence-path coverage.
