fix: update remaining general-purpose refs to gsd-executor

- execute-phase.md: wave execution example now uses gsd-executor
- execute-plan.md workflow: subagent spawning uses gsd-executor
- continuation-prompt.md: continuation spawning uses gsd-executor
- Remove obsolete subagent-task-prompt.md reference
