Show complexity in task detail view

Excellent! The implementation is complete and all tests pass. Let
me pro

I successfully implemented the task to show complexity in the task
detai

1. **File Modified**: `Omni/Task/Core.hs` 2. **Function**:
`showTaskDetailed` 3. **Change**: Added complexity display after the
Priority line (lines 1

```haskell case taskComplexity t of
  Nothing -> pure () Just c -> putText ("Complexity: " <> T.pack
  (show c) <> "/5")
```

This code: - Checks if the task has a complexity value set - If
`Nothing`, does nothing (no complexity line is shown) - If `Just c`,
displays "Complexity: X/5" where X is the complexity valu

- ✅ `bild --test Omni/Task.hs` passed successfully - ✅ `lint
Omni/Task/Core.hs` passed with no hlint warnings or errors - ✅ All
existing tests continue to pass

The implementation matches the exact specification provided in the task
