feat(simulation): serve atlas layer requests over the bridge — completes #969 (D-225)

Browse Source 
Closes the server-side layer-stream loop. serve_atlas_requests (PreInput) drains
the AtlasRequestBuffer and runs each through handle_atlas_request (cache hit ->
Ready; miss -> resolve via BodySourceResolver + enqueue an Immediate AnalyzeBody
-> Pending), buffering AtlasLayerResponses. send_atlas_responses (PostSnapshot)
flushes them to the client. main.rs wires BodySourceResolverResource (base root
= systems.db's 3rd ancestor; mod roots layer on later). Misses flow through the
#968 background tier and a re-request hits the now-warm cache.

Full path now live server-side: client request -> receive() demux -> serve ->
proxy -> (cache | queue+cascade) -> response -> client. The client half (send
request, decode response, render overlays) is #960.
