ad-hoc-profile-load
Load an agent profile on demand to adopt a specific role for the current session. Applies the profile's identity, governance scope, boundaries, and initialization declaration without requiring a running mission. Triggers: "act as the architect", "load the reviewer profile", "switch to implementer", "use the researcher persona", "start a session as planner", "adopt the curator role", "initialize profile", "assume the designer identity". Does NOT handle: mission advancement (use runtime-next), charter interview/generation (use charter-doctrine), or profile creation (use the charter synthesize workflow / edit the profile YAML directly).
