Greptile Summary

This PR adds a packaged React cockpit and a reconnecting WebTransport relay path from robot streams to browser viewers.

• Adds robot registration, manifests, subscriptions, reliable stream framing, and relay lifecycle management.
• Integrates local and remote relay options into the robot CLI and global configuration.
• Builds and packages cockpit assets in release distributions and adds Python, Deno, browser, and protocol tests.

Confidence Score: 3/5

The stale cockpit state and broken release wheel smoke path should be fixed before merging.

Robot removal leaves the previous manifest visible in the cockpit, and clean cibuildwheel validation now raises because its workflow does not generate the newly mandatory cockpit distribution.

Files Needing Attention: web/cockpit/src/session/session.ts, setup.py, .github/workflows/release-build-check.yml

Important Files Changed

Filename	Overview
dimos/web/relay_bridge/relay_bridge_module.py	Adds lazy stream subscriptions, local relay supervision, and reconnect/respawn behavior.
web/relay/registry.ts	Adds robot registration, viewer watches, channel subscriptions, and forwarding policy coordination.
web/cockpit/src/session/session.ts	Implements cockpit session orchestration but retains stale manifest/channel state after the selected robot disappears.
web/cockpit/src/session/transport.ts	Adds WebTransport setup, certificate pinning, protocol checks, and reconnect backoff.
setup.py	Copies relay and cockpit assets into wheels but introduces an unmet prerequisite in the release smoke workflow.
.github/workflows/release.yml	Builds cockpit assets before creating release sdists and wheels.

   Wheel smoke build lacks cockpit assets

   When the release wheel smoke workflow runs cibuildwheel from a clean checkout, CIBUILDWHEEL=1 reaches this new check without first building web/cockpit/dist, causing the validation job to abort with the cockpit-dist RuntimeError instead of producing a wheel.

Stale manifest survives robot removal

When the watched robot disconnects and the relay publishes an empty robot list, this branch clears the selected robot but retains the previous manifest and channels, causing the cockpit to report "no robot" while continuing to display the disconnected robot's stale channel table.
