Lay the backend groundwork so the existing mock-agent can run inside
local_docker containers — needed for real-Docker E2E tests that don't
require Anthropic/OpenAI API keys.
Container builder bind-mounts a host mock-agent binary at
/usr/local/bin/mock-agent when KANDEV_MOCK_AGENT_LINUX_BINARY is set
(or build/mock-agent-linux-amd64 sits next to the kandev binary), the
same pattern already used for agentctl. MockAgent.BuildCommand always
resolves via PATH so the same command works on host (E2E PATH includes
bin/) and in containers (mounted at /usr/local/bin/mock-agent).
Mock now declares non-nil empty RemoteAuth so it counts as a
remote-capable agent. The remoteauth catalog includes specs even with
zero methods, and the frontend gating helper treats an empty-method
spec as "no credentials needed" — letting mock-agent pass the
configure-on-executor check that hides uncatalogued agents on remote
executors.
repositoryCloneURL falls back to the local origin remote URL when the
repo has no provider info, so local-only repos with a real remote
(including file:// remotes used in E2E) work on remote executors that
clone inside the container.
Makefile: build-mock-agent-linux target mirrors build-agentctl-linux.
