## Message

```
Fix searching for full SHA-256 commit hashes in Git graph (#63371)

# Objective

Search in the Git graph does not support full commit hashes in SHA-256
formatted repos, while SHA-1 formatted repos work fine.

## Solution

Use existing constants in the `git` crate instead of hardcoded values
when checking for a commit hash query.

## Testing

Added a regression test for valid SHA-1 and SHA-256 commit hash lengths,
plus rejection of hashes longer than the max length.
