Robert Brennanandopenhands 35555bac11 feat: enable sub-agent delegation via task_tool_set (#509) ...

The agent-server already registers `task_tool_set` (TaskToolSet) at
startup via openhands-agent-server/openhands/agent_server/tool_router.py
and preloads the built-in sub-agents (code-explorer, bash-runner,
web-researcher, general-purpose) through `register_builtins_agents`.
However, agent-canvas never asked for the tool in the agent spec it
sends on POST /api/conversations, so the LLM had no way to delegate.

Add `task_tool_set` to the tools list assembled by `getAgentTools()`,
gated by the existing `isAgentServerToolAvailable` capability probe so
older agent-servers that don't advertise it in /api/server_info's
`usable_tools` are skipped cleanly.

TaskAction / TaskObservation events render through the existing default
event content path, so no new visualizer is required to ship this.
