feat(cli): add system metrics to telemetry and expand doctor command (#110)

* feat(cli): add system metrics to telemetry and expand doctor command

Enrich render telemetry with device/environment metadata (CPU, memory,
OS, Docker/CI/WSL detection) following patterns from Next.js and
Turborepo. Add speed_ratio (render time / composition duration),
per-frame capture timing, and resource usage to render events.

Expand the doctor command with CPU, memory, disk, /dev/shm, and
environment checks to help debug rendering issues on user machines.

* fix(cli): invert speed_ratio to match experiment-framework convention

composition_duration / render_time — higher is better, >1 means faster
than realtime. Matches magic_edit.render.speed_ratio in experiment-framework.

* fix(cli): wire errorMessage into render error telemetry

Address review feedback — the errorMessage field was declared in the
trackRenderError interface but never populated.

* feat(cli): add render telemetry to embedded studio server

Track render_complete and render_error from the studio's render API
endpoint (hyperframes dev). Uses dynamic imports so telemetry is
resolved at call time within the CLI package — no telemetry coupling
added to @hyperframes/studio or @hyperframes/producer.
