Promote the `mvp-system` workspace library crate to a standalone application at `apps/myelin`, rebranding the MVP system along with its binaries, node image, and spec.
- workspace `Cargo.toml`: swap member `crates/mvp-system` -> `apps/myelin` and drop `apps` from `exclude` so the app joins the workspace
- `apps/myelin/Cargo.toml`: declare package `myelin` with `autobins = false` and explicit `[[bin]]` targets `myelin-worker`, `myelin-orchestrator`, `myelin-chat`
- `apps/myelin/src`: move the whole `mvp-system` source tree and rebrand module surfaces (`chat/mod.rs`, `prompt/mod.rs`); add `bin/chat.rs` (`myelin::run_chat_from_args`) and delete the old `mvp_chat.rs`
- `apps/myelin/node-image`: relocate the worker image assets from `apps/mvp-node/` (Dockerfile, Dockerfile.base, tinygrad_worker.py, entrypoint, e2e script) and rename `MVP_SYSTEM_SPEC.md` -> `MYELIN_SPEC.md`
- `xtask`: rewrite build/reference paths for the rename (~1000-line churn); add `crates/dashboard/ACTOR_PANEL_SPEC.md`

Replace the sprawl of narrow per-implementation test files (and the inline #[cfg(test)] modules embedded in source) with a small set of black-box behavior-guarantee suites keyed to the public modules, per the BEHAVIOR_GUARANTEES spec.
- tests/mod.rs: cut the test module list to local_e2e/node/observability/orchestration/prompt/staging/transport (+local_mock), removing bootstrap_datastream/relay_provisioning/run_plan/stage_controller/shard_*/weight_*/tx_rx_edge_actor/worker_edge_adapter/telemetry/shared_ring_helper_abi/orchestrator_run_fsm files
- add tests/orchestration_guarantees.rs (1074 lines) and staging_guarantees.rs (747) as black-box contract suites over the public RunPlan and StageController surfaces, referencing specs/BEHAVIOR_GUARANTEES.md
- add focused node_guarantees, prompt_guarantees, and transport_guarantees suites covering node-agent runtime-ready reporting, prompt defaults/terminality, and endpoint-advertisement relay masking
- rename local_mock_pipeline_integration to local_e2e_guarantees and observability_surface_guarantees to observability_guarantees
- strip the large inline #[cfg(test)] mod tests blocks from source files (orchestration/app.rs -3215, chat/runtime.rs -790, node/worker_node_runtime.rs -522, vastai/mod.rs, gguf_shard/shard_fetch, etc.) and the #[path]-registered shard_* test mods from lib.rs
- Cargo.toml: drop the harness=false mvp_chat_mock [[test]] target, and remove the python_worker_protocol integration test

- Split arena/ring/object-record into a new data-plane crate and node/plugin contracts
into a provisioning crate.
- Reorganize mvp-system into orchestration, staging, node, chat, and worker modules;
extract binaries into chat/runtime and node/worker_node_runtime.
- Add MVP_SYSTEM_MODULE_BOUNDARY_SPEC.

Distribute only each stage's GGUF layer slice over HTTP, add sampler and weight-load health telemetry, and harden node-image build, orchestrator provisioning, and the VastAI lease/search path.
- gguf_shard (new): StageShardPlan and plan_stage_shard parse the GGUF directory and compute coalesced per-stage tensor byte ranges; materialize_stage_shard_http fetches only those ranges (plus the header) to build a stage-local GGUF, with planned_fetch_bytes accounting.
- orchestrator_app: build a BTreeMap<u32, StageShardPlan> from the run plan for HuggingFace sources, thread stage_shard_plan through StageProvisionWire and weight-load, emit stage_shard_plan summaries, and add liveness phases (prefetching/fetching_stage_shard, cache_ready, stage_shard_ready).
- worker_node: add a stage-shard-fetcher subcommand and materialize_stage_shard_with_process that spawns the fetcher, streams its stdout/stderr as stage_shard_fetch events (StageShardCacheReady/StageShardReady), caches under MVP_MODEL_CACHE_DIR, and feeds the local shard path into load_weights.
- worker_node: add NODE_SAMPLER_CHANNEL and SamplerHealth telemetry (gpu/cpu/net samplers emit started/waiting/ready/failed) plus structured helper stdout/stderr streaming (wait_for_helper_event/drain_worker_stderr).
- node_image: expand node-image build/push handling for the deploy path.
- tools/vastai: extend lease, search, and types and drop unused pricing code.

Add mvp-system/src/mvp_chat.rs with a run_from_args entrypoint wiring swactor runtime,
dashboard, chat datastream, and a PromptLoop. Add a mock integration test; refresh
mvp-chat and MVP_SYSTEM specs.

Stand up an interactive end-to-end chat over a CUDA GPU, provisioning a Dockerized node that loads a GGUF model and serves prompts over TCP.
- prompt_rpc: add the newline-JSON prompt protocol (`SubmitPrompt` + `PromptEvent::{TextDelta,Done,Fault}`) carried over TCP
- mvp_chat: add an interactive REPL client connecting to the prompt RPC port (default 127.0.0.1:19777)
- mvp_orch_one_node / mvp_one_node_chat: add the single-node orchestrator that provisions a `LocalDockerPlugin` node, loads `bartowski/Llama-3.2-1B-Instruct-GGUF` (Q4_K_M), and exposes the prompt RPC listener with boot/route/weight timeouts
- mvp_node: add the GPU worker binary that spawns `tinygrad_worker.py` (default device CUDA) and ships runtime telemetry via a `ClusterFrameSink`
- vastai_provisioning / bootstrap_datastream: add the vast.ai provider adapter (`VastAiProvisioningConfig`, `VastAiLeaseClient`) wrapping `swactor_vastai`, plus a bridge that folds provision stdout onto a per-node datastream
- apps/mvp-node: add CUDA base/runtime Dockerfiles (nvidia/cuda 12.6.3, tinygrad 0.12.0, sshd), `mvp_entrypoint.sh` (sshd + mvp-node, held for postmortem), `local_docker_e2e.sh`, the GGUF tinygrad worker, and one-node-chat/bootstrap/vastai guarantee tests

Fold the fragmented distribution swim/routing/gossip tests into swim_core, routing,
and swim_actor. Prune the dashboard tui and command surfaces. Add mvp-system actors
(node_agent, orchestrator, stage_controller), the local_e2e harness, and gpu worker
e2e.
