resolveModelInternal() was converting 'opus' to 'inherit', assuming
the parent process runs on Opus. When the orchestrator runs on Sonnet
(the default), 'inherit' resolves to Sonnet — silently downgrading
quality profile subagents.
Remove the opus→inherit conversion so the resolved model name is
passed through directly. Claude Code's Task tool now supports model
aliases like 'opus', 'sonnet', 'haiku'.
