/**
* A per-agent persona as a composable row.
*
* `dsh-system-prompt` owns the global persona as its own config, and registers
* that section unconditionally — so this row is **scope-only**. Mounted inside
* an agent preset it shadows the deployment persona for that one session,
* exactly like the per-child persona `dsh-subagent` installs; mounted globally
* it collides with the registry's own registration and fails loud.
*
* That constraint is the reason the row exists. An agent preset cannot mount
* the prompt registry itself, so without a row of its own a preset could
* change an agent's tools but never its identity.
* @module @deepseek-ai/dsh-persona
