Replace the opencode GrokProvider with GrokCliProvider: reuses the orchestrator's
shared mount/auth/git assembly (gateway + identity) exactly like the Claude path,
mounts the host ~/.grok/auth.json read-only (SuperGrok subscription) instead of
injecting an xAI key, and sets the slim env the grok-cli entrypoint + renderer
read (ROBOCO_AGENT_ID for per-role flags, model, mcp-config, prompt). Provider
routing fields are blanked before the shared step so the grok endpoint is never
mislabelled ANTHROPIC_*. Per-role permission logic now lives in grok_cli_config,
so the provider is slim. Registry/orchestrator/exports updated; provider tests
rewritten for the CLI behavior (no XAI key, auth mount present/absent).
