Review Comment:
   I would be very cautions with this pre-commit validations, because it need 
to handle a lot of stuff the nice example is `pydantic` which use annotations 
in runtime , and put them under `if TYPE_CHECKING` block might lead serious 
problem
   
   For example lets use example from the [main 
page](https://docs.pydantic.dev/latest/) of `pydantic` documentation
   
   This is work fine
   
   ```python
   from datetime import datetime
   from typing import Tuple
   
   from pydantic import BaseModel
   
   
   class Delivery(BaseModel):
       timestamp: datetime
       dimensions: Tuple[int, int]
   
   
   m = Delivery(timestamp='2020-01-02T03:04:05Z', dimensions=['10', '20'])
   ```
   
   and this one would fail on model compilation
   ```python
   from typing import Tuple, TYPE_CHECKING
   
   from pydantic import BaseModel
   
   if TYPE_CHECKING:
       from datetime import datetime
   
   
   class Delivery(BaseModel):
       timestamp: datetime
       dimensions: Tuple[int, int]
   ```
   
   ```console
   /Users/taragolis/.pyenv/versions/3.9.10/envs/narrative/bin/python 
/Users/taragolis/Library/Application 
Support/JetBrains/PyCharm2023.2/scratches/pydantic_sample.py
