/**
 * CoordinatorActivateHandler — runtime activation decision for the
 * coordinator stage.
 *
 * Built-time stage selection cannot see runtime ctx (selectedSkills are
 * populated only after `skill-select` runs). This handler evaluates the
 * configured `IActivationStrategy` against REAL ctx state and writes
 * `ctx.coordinatorActive`. Coordinator and tool-loop stages gate on this
 * flag via `when:` predicates so the activation decision honours runtime
 * skill selection.
 *
 * Reads:  `ctx.subAgents`, `ctx.selectedSkills`.
 * Writes: `ctx.coordinatorActive`.
