Whether to preserve model specifications in Claude Code humanlayer commands and agents.
When false (default), the model: line is stripped from frontmatter, allowing Claude Code
to use its default model selection.
When true, the model: specifications from the source files are preserved, allowing
commands to specify opus/sonnet/haiku explicitly.
