<objective>
Run the single pre-plan gate for a phase: spawn the assumptions analyzer
against the codebase, close the gray areas it surfaces with a few targeted
questions, lock falsifiable acceptance criteria, and ask exactly once whether
the phase is too big for one plan. Writes `.planning/phases/<N>/CONTEXT.md`
for /cad-plan to read. Optional - /cad-plan runs without it.
