Searches normalised Catalyst tasks within the current tenant.

This endpoint provides a lightweight, deterministic search intended for dashboards and automation tools such as Zapier, rather than full-text search.

Search behaviour:

• Performs a case-insensitive substring match over task title and details.
• Supports optional filtering by canonical domain and priority.
• Automatically excludes internal system-derived tasks.

Pagination:

• Results are paginated using limit and offset query parameters.
• The count field in the response represents the total number of matched tasks, not just the number returned in the current page.

Typical Zapier usage:

• Find an existing task before updating it.
• Locate tasks for bulk updates or notifications.
• Pair with 'Send Task to Catalyst' when no matching task is found.
