codeg v0.14.3

Release version 0.14.3

• feat(delegation): Added per-agent default options so each sub-agent type can carry its own preset CLI flags and spawn parameters when invoked via delegate_to_agent.
• feat(delegation): Replaced the delegation timeout mechanism with MCP-native cancellation, allowing the host to cleanly cancel long-running sub-agent calls without forcing a hard timeout.
• feat(workspace): Added a maximize toggle for the file pane so users can expand the file browser to fill the workspace.
• test(delegation): Extended Windows end-to-end coverage to spread the new agent_defaults configuration through delegation flows.
