refactor: rename container references to agent across codebase

- container-runner.ts → agent-runner.ts
- ContainerInput/Output → AgentInput/Output
- ContainerConfig → AgentConfig
- runContainerAgent → runAgentProcess
- CONTAINER_TIMEOUT → AGENT_TIMEOUT (with env fallback)
- MAX_CONCURRENT_CONTAINERS → MAX_CONCURRENT_AGENTS
- containerName → processName, isTaskContainer → isTaskProcess
- DB column container_config kept as-is (backwards compat)
