fix: remove helper function _normalize_pattern

[filipchristiansen]

This PR removes the helper function _normalize_pattern (and its use inside _parse_patterns)

Before

• gitingest -e "*/test_*"

    │   ├── conftest.py
    │   ├── .pylintrc

    │       ├── test_git_host_agnostic.py

• gitingest -e "**/test_*"
• gitingest -e "/test_*"

    │   ├── conftest.py
    │   ├── .pylintrc
    │   └── query_parser/
    │       └── __init__.py

Now:

• gitingest -e "*/test_*": Same behaviour

• gitingest -e "**/test_*": Same behaviour

• gitingest -e "/test_*": Excludes no tests (matches only at project root)

File	Description

Comments suppressed due to low confidence (2)

• Add unit tests for patterns with leading separators (e.g., '/test_*') to verify that normalization is no longer applied and patterns are returned exactly as provided.

    return parsed_patterns

src/gitingest/query_parser.py:310

• Update the docstring of _parse_patterns to reflect that leading separators are no longer stripped and wildcards are not appended automatically.
