feat(delegation): add configurable reasoning_effort for subagents

Browse source 
Add delegation.reasoning_effort config key so subagents can run at a
different thinking level than the parent agent. When set, overrides
the parent's reasoning_config; when empty, inherits as before.

Valid values: xhigh, high, medium, low, minimal, none (disables thinking).

Config path: delegation.reasoning_effort in config.yaml

Files changed:
- tools/delegate_tool.py: resolve override in _build_child_agent
- hermes_cli/config.py: add reasoning_effort to DEFAULT_CONFIG
- tests/tools/test_delegate.py: 4 new tests covering all cases
