permanence.domains.meridian.tasks — social-drama task templates.

The task TEMPLATE DEFINITIONS themselves live in
``permanence.tasks.task_bank.TaskBank._build_templates`` for historical
reasons (the bank holds both Meridian and DevTools templates in one method).

This module exposes a Meridian-only surface by filtering the bank down to
the set of task ids the Meridian domain owns. If we later physically move
each template dict entry into this file, callers do not change.
