refactor: migrate to hatchling and simplify test setup

[sicksubroutine]

This pull request introduces updates to the project's build system, dependencies, and testing structure. The most notable changes include migrating from setuptools to hatchling for the build system, removing the need to modify sys.path in test files, and simplifying patching logic in tests for better readability and maintainability.

The Build system is much faster and all of the sys path manipulation is no longer needed. All tests are still passing.

Build System and Dependency Updates:

• Migrated from setuptools to hatchling as the build backend in pyproject.toml. This involved updating the requires field under [build-system] and removing tool.setuptools configurations.
• Added License :: OSI Approved :: MIT License to the classifiers section in pyproject.toml.

Test File Improvements:

• Removed sys.path modifications from all test files, eliminating the need for manual inclusion of the project directory for testing. This change affects files such as tests/test_config.py, tests/test_content_processing.py, tests/test_llm.py, tests/test_main.py, and tests/test_navigation.py. [1] [2] [3] [4] [5]
• Simplified patching logic across test files by reducing multiline with patch statements into single-line statements for better readability. Examples include tests/test_content_processing.py and tests/test_llm.py. [1] [2]

Pull Request Overview

This PR migrates the Python build backend to Hatchling, removes ad-hoc sys.path hacks from tests, and streamlines test setup by collapsing multi-line patches and concatenations into single-line expressions.

• Switched from setuptools to hatchling in pyproject.toml and added basic pytest settings.
• Stripped out all manual sys.path inserts in test files, relying on pytest’s configuration instead.
• Refactored test code to use single-line statements for list/tuple definitions, patch contexts, and async loops for readability.

tests/test_views.py:1

• [nitpick] Consider grouping imports into standard library, third-party, and local sections (with blank lines between) to comply with PEP8 import ordering and improve readability.

from unittest.mock import Mock

pyproject.toml:63

• Verify that the pytest pythonpath setting under tool.pytest.ini_options is supported without additional plugins; otherwise tests may still fail to locate the src package.

pythonpath = ["src"]

[Copilot]

[nitpick] Using exec inside a lambda to raise an exception is hard to read; consider defining a simple property that directly raises for clarity in the test.

Suggested change

	self.mock_content_widget.max_scroll_y = property(lambda self: exec('raise Exception("Test error")'))
	def raise_exception():
	raise Exception("Test error")
	self.mock_content_widget.max_scroll_y = property(lambda _: raise_exception())

This looks great!

I added a formatting check in the CI, just run uv run ruff format . and it should be all set to merge in!

[sicksubroutine]

Done! Also on the other PR I just added :) That's probably all I'll do for this weekend, but I might take a crack at a few other things during breaks at work this week.

Amazing, thank you!
