Fix Issues in edit_task.go — Double Date Formatting and Redundant Annotation Block Execution

[inderjeet20]

Description:

The edit_task.go file in the Taskwarrior (tw) layer contains two critical issues that need to be addressed:

1. Double Date Formatting Produces Invalid Datetimes
   The file appends T00:00:00 to all date strings, even when the controller has already converted ISO dates to Taskwarrior format. This results in invalid datetime strings like "2026-01-28T14:30:00T00:00:00", which Taskwarrior rejects.

2. Redundant Annotation Block Execution
   The condition len(annotations) >= 0 is always true, causing the annotation regeneration block to execute unnecessarily, even when no annotations are provided. This leads to redundant operations, such as deleting and re-adding all existing annotations.

---

Steps to Reproduce:

1. For Double Date Formatting:

   • Submit a request to edit a task with a wait or due field containing a full ISO datetime (e.g., "2026-01-28T14:30:00").
   • Observe that the resulting Taskwarrior command includes an invalid datetime string.

2. For Redundant Annotation Block Execution:

   • Submit a request to edit a task without any annotations.
   • Observe that the annotation regeneration block is executed, deleting and re-adding all existing annotations.

---

Expected Behavior:

1. Double Date Formatting:

   • The edit_task.go file should only append T00:00:00 to date-only strings (e.g., "2026-01-28") and leave full datetime strings unchanged.

2. Annotation Block Execution:

   • The annotation regeneration block should only execute when len(annotations) > 0.

---

Actual Behavior:

1. Double Date Formatting:

   • The edit_task.go file appends T00:00:00 to all date strings, resulting in invalid datetime strings.

2. Annotation Block Execution:

   • The annotation regeneration block executes regardless of whether annotations are provided, due to the len(annotations) >= 0 condition.

---

Suggested Fix:

1. Double Date Formatting:

   • Add a check in edit_task.go to determine whether the input string is a date-only string or a full datetime string before appending T00:00:00.

2. Annotation Block Execution:

   • Update the condition to len(annotations) > 0 to ensure the block only executes when annotations are provided.
