compute orchestration (#763)

- Added local process runners for Linux/Wine, Mac with some sandboxing support
- Horde & Nomad provisioning for development and testing
- Client session queues with lifecycle management (active/draining/cancelled), automatic retry with configurable limits, and manual reschedule API
- Improved web UI for orchestrator, compute, and hub dashboards with WebSocket push updates
- Some security hardening
- Improved scalability and `zen exec` command

Still experimental - compute support is disabled by default
