Maxime Ellerbach fd6aed87b7 sync engine: robust per-chunk anchor via predict_action_chunk probe ...

Replace the relative-action anchor mechanism from "adding relative actions
to sync engine" with one that detects fresh chunks through the public
predict_action_chunk contract instead of introspecting the policy's private
_action_queue. Drops set_hold/_hold_state in favour of a set_cached_state
snapshot/restore, keeps select_action on the hot path (so the prediction-
visualization path is unaffected), and refreshes the anchor every tick for
policies that never chunk.
