feat(runtime): add mvp runtime process discovery service

[ramizpolic]

Summary

This PR introduces an MVP runtime service that enables process discovery and lifecycle management for OASF agent processes.

Key Changes

New gRPC API (agntcy.dir.runtime.v1)

• RuntimeService.CreateProcess — Creates and starts a process from an OASF record data (for now, only container image is supported)
• RuntimeService.ListProcesses — Streams all running DIR-managed processes with filtering support

Proto Definitions

• Process message with record metadata, PID, runtime type, creation timestamp, and annotations
• CreateProcessRequest (takes record_cid) and ListProcessesRequest (takes filters)

Docker Runtime Implementation

• Uses agntcy.dir.record/cid container label to identify DIR-managed containers
• Automatically extracts docker_image locator from OASF records to run containers
• Lists only running containers with the DIR selector label

Server Integration

• New RuntimeAPI interface for pluggable runtime backends
• Runtime controller wired into the gRPC server
• Disables OASF API validation in dev task for easier testing

Open Questions

• How to discover processes not explicitly labeled at creation time (e.g., docker run or kubectl without DIR involvement)
• Proposed solution: .well-known/oasf endpoint convention where OASF-compliant agents self-report
