jif c9296fa1a9 Deprecate the multi_agent feature flag (#59479) ...

## What changed

Mark `[features].multi_agent` as deprecated while keeping it enabled by default and preserving its control of the V1 fallback.

Emit a startup warning when a user or project configuration explicitly sets the flag. The warning points to `[agents].enabled = false` for disabling subagent tools, with an exception when `[features].multi_agent_v2` is enabled. Session-only overrides do not trigger the warning.

## Testing

Add configuration-loader coverage for explicit user and project settings, including a project setting overridden by a session flag, and for session-only overrides. Update the default-enabled feature check to allow deprecated features.
