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::`.
