Reorganize crates/mvp-system from flat files into domain module trees (chat, node, node_data, observability, orchestration, prompt, staging, transport, worker) with documented mod.rs boundaries, and drop the stale inline spec docs.
- lib.rs: replace ~20 flat mod declarations with one pub-mod-per-domain (chat/node/node_data/observability/orchestration/prompt/staging/transport/worker)
- node/, chat/, observability/, orchestration/, staging/, prompt/, transport/, worker/: add mod.rs files with module-boundary doc comments and re-exports (e.g. chat re-exports run_from_args; orchestration re-exports RunConfig/RunId/GgufSource/TokenizerSource/ProviderKind)
- orchestration: group providers under provider_adapters/{docker_cluster,relay,vastai} and fold engine_builder/, config, run_fsm, run_plan, provisioning, resource_inventory, membership_readiness, and token_endpoint under orchestration/
- transport: consolidate codec registration into transport/codec_registry::register_mvp_actor_codecs (was crate::actors::register_mvp_actor_codecs) and rename actors/codec.rs to transport/json_codec.rs
- rename and relocate files into their domains (arena_manager->node_data/arena, actors/node_agent->node/actor, actors/orchestrator->orchestration/actor, stage_controller->staging/actor, telemetry/dashboard_view/etc->observability/, benchmark_observability->observability::benchmark, edge_establisher->node::edge_lifecycle, prompt_rpc->prompt::rpc) and update all crate:: imports accordingly
- remove the stale crates/mvp-system/specs/*.md (MVP_SYSTEM_MODULE_BOUNDARY_SPEC, mvp_chat, orchestrator) now that module boundaries live in mod.rs docs

Add endpoint-address masking and a relay-only advertisement path so the multinode Docker mvp-chat scenario can run with direct addresses stripped.
- endpoint_advertisement: add EndpointAddrMask (Full/RelayOnly) parsed from --endpoint-addr-mask/MVP_IROH_ENDPOINT_ADDR_MASK, and advertised_endpoint that rebuilds an EndpointAddr from relay URLs only, rejecting relay-only without a relay URL
- orchestrator_app: mask the coordinator endpoint before advertising it, thread the masked collector endpoint into datastream subscribe/runtime-ready acks, surface endpoint_addr_mask/has_relay/direct_addr_count in iroh_driver and node_spec events, forward the mask env to workers, and add a 60s RUNTIME_READY_TIMEOUT to the runtime-ready barriers
- worker_node: advertise the masked self endpoint in the iroh_driver ready and coordinator_join events and propagate it through runtime_ready_local and PendingRuntimeReady
- mvp-chat: add --relay-mode/--relay-url/--endpoint-addr-mask plus a [relay] toml section, require (with a Vast.ai fallback) a relay URL when relay-only, and forward all three to the orchestrator CLI
- node_image: resolve the worker binary to a workspace-relative path for the Docker COPY via docker_build_context_path, rejecting paths outside the build context
- xtask/specs: run MultinodeDocker with --relay-mode default --endpoint-addr-mask relay-only, add dump-log fact checks for relay-masked orchestrator/node/coordinator advertisement, and document the mask/relay flags in mvp_chat.md
