fix(ci): repair Python 3.10 syntax, import sorting, and coverage matrix

Resolves failing CI jobs on PR #1 by:

1. Removing nested quotes inside f-strings for Python 3.10 compatibility.

2. Fixing I001 import-sorting violation in utils.py via ruff format.

3. Appending the missing 'tests/unit/llms/serpapi' test path to the CI shard matrix in main.yml to satisfy assert-ci-coverage.
