* test(#3936): quick research dispatch must use researcher persona/model
Regression tests for the planner-persona leak in quick's Step 4.75
research dispatch: init quick emits researcher_model, the workflow
resolves AGENT_SKILLS_RESEARCHER and parses researcher_model, and the
researcher dispatch uses the researcher persona/tier while planner and
executor dispatches keep their own.
* fix(#3936): dispatch quick research with researcher persona and model
cmdInitQuick now emits researcher_model (parity with the plan-phase
init), quick.md resolves AGENT_SKILLS_RESEARCHER and parses the new
field, and Step 4.75's dispatch swaps ${AGENT_SKILLS_PLANNER}/
{planner_model} for the researcher's own persona and tier. The #2517
model-omission list gains researcher_model.
