Create Recurrence Task Table

Implementation description

Added a new migration to create the recurrence_tasks table to support Weekly, Biweekly, Monthly, and Annually recurring tasks.
Added RecurrenceTask model with fields: task_id, days, cadence, end_date, and exclusions.
Updated Task model to include a @hasone relationship to RecurrenceTask so recurrence details can be retrieved via include: ["recurrence"]

Steps to test

1. Create a test task_template

INSERT INTO task_templates (task_name, category, instruction)
VALUES ('Test Template', 'Misc.', 'Test Instruction')
RETURNING id;

Copy the returned id (call it TEMPLATE_ID).

2. Create a test task linked to that template

INSERT INTO tasks (pet_id, task_template_id, created_at)
VALUES (101, TEMPLATE_ID, NOW())
RETURNING id;

Replace TEMPLATE_ID with the value from Step 1.
Copy the returned id (call it TASK_ID).

3. Add a recurrence rule for that task

INSERT INTO recurrence_tasks (task_id, days, cadence, end_date, exclusions)
VALUES (
  TASK_ID,
  ARRAY['Mon','Wed']::enum_recurrence_tasks_days[],
  'Weekly',
  '2025-03-01',
  ARRAY['2025-02-10','2025-02-24']::date[]
);

Replace TASK_ID with the value from Step 2.

4. Verify the recurrence record exists

SELECT * FROM recurrence_tasks WHERE task_id = TASK_ID;

If this returns a row, the recurrence was created correctly and can be retrieved via task.recurrence.

Overall, LGTM (haven't tested yet). Left a few minor nitpicks to change.
