Hongming Wang d4cead5002 chore: extract ContextMenu Zustand fix + a2a_proxy local-docker SSRF bypass + workspace-server Dockerfile GID entrypoint
Three small, non-overlapping fixes extracted from closed PR #1664:

1. canvas/src/components/ContextMenu.tsx — Replace the useMemo-over-nodes
   pattern with a hashed-boolean selector (s.nodes.some(...)) so Zustand's
   useSyncExternalStore snapshot comparison is stable. Resolves React
   error #185 (infinite render loop). Moves the child-node list derivation
   into the delete handler via getState() so the render path no longer
   allocates a fresh array.

2. workspace-server/internal/handlers/a2a_proxy.go — Allow the
   Docker-bridge hostname path (ws-<id>:8000) to skip the SSRF guard in
   local-docker mode. Gated on !saasMode() so SaaS deployments keep the
   full private-IP blocklist (a remote workspace registration can't claim
   a ws-* hostname and reach a sensitive VPC IP).

3. workspace-server/Dockerfile — Add entrypoint.sh that discovers the
   docker.sock GID at boot and adds the platform user to that group, then
   exec's su-exec to drop privileges. Lets the platform container reach
   the host docker socket without running as root.
