Add actor-backed manual node provisioning, control-plane endpoints, and fleet UI assets with durable provider lifecycle handling.
Simplify Myelin orchestration, node runtime, staging, and telemetry paths while removing obsolete engine-builder, dashboard-view, and local-mock implementations.
Align runtime delivery, data-plane, distribution, job-runner, process, telemetry, dashboard, Vast.ai integrations, and their tests with the revised actor and transport contracts.
The crate is the per-node metrics/logging pipe with a universal
subscriber endpoint, but "datastream" kept getting misread as a general
messaging plane. Rename crate, module paths, and public API
(`DatastreamEndpoint` → `TelemetryEndpoint`, etc.) so misuse is visible
on sight.
Renamed contracts (all in-repo producers/consumers migrated):
- env vars `MYELIN_DATASTREAM_*` → `MYELIN_TELEMETRY_*`
- artifact `datastream.ndjson` → `telemetry.ndjson`
- actor names `telemetry-publisher` / `telemetry-sink`
- wire ALPN `swactor/telemetry/0`
- `DATASTREAM_SPEC.md` → `TELEMETRY_SPEC.md`
Also fixes two latent test breaks: `process` and `iroh-driver` tests
imported `DatastreamEvent` from the crate root, which was never
re-exported; they now use the observer path `telemetry::frame::`.
Trim the datastream crate to its dumb-pipe core: drop the frame-timing sidecar, make mux positions gap-free for accepted frames, and simplify the endpoint fanout.
- mux: defer position assignment from submit to drain so an overflowed submission no longer consumes a position (no synthetic gaps); submit now returns bool and the Mutex<Receiver> is removed since positions are assigned only to accepted frames
- endpoint/mux: switch from std::sync::mpsc to crossbeam-channel and drop per-event event_matches_request filtering — request filters now apply only to the initial catalog snapshot, and future events broadcast to all subscribers
- endpoint (DeliveryFanout): snapshot sender handles under the lock and deliver outside it via FanoutTarget/FanoutReport, so large batches or slow subscribers no longer block subscribe/snapshot control-plane ops
- emit/endpoint/producer: drop set_frame_timing_enabled/frame_timing_enabled and the Position return from submit_record/submit_text/submit_bytes, and add submit_text_owned taking owned String
- timing/lib/spec: delete the timing module and FRAME_TIME_CHANNEL/FRAME_TIME_CHANNEL_ID/FrameTimeSample re-exports (including the auto-registered timing channel in ChannelCatalogState) and renumber the DATASTREAM_SPEC.md section references across frame/ingest/store/mux
- tests: remove the 567-line shared datastream_support/mod.rs harness

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.
