Include changelog links for major release upgrades

[nickmoreton]

This pull request introduces several improvements to dependency reporting, including enhanced update type detection, better handling of repository URLs for major updates, and refined HTML output styling. Additionally, it updates tests to reflect these changes and ensures consistency in terminology across the codebase.

Dependency update handling:

• src/helpers.py: Added a new calculate_update_type function to determine if an update is major, minor, or a patch based on version comparison. Integrated this logic into package_table_row to reflect update types in the status and adjust styling accordingly. Major updates now include repository URLs when available.
• src/managers/package.py: Introduced a new repository_url property to retrieve repository URLs from package metadata, prioritizing keys like "Changelog" and "Repository."

HTML output improvements:

• src/reporters/html.py: Enhanced _table_dependency_row to handle statuses with newlines (e.g., repository URLs for major updates) and display clickable links. Added AI chat request suggestions for major updates. Updated _gather_status_class to use distinct colors for update types (major, minor, patch) and refined fallback styling.

Terminology consistency:

• src/check_local.py and src/check_remote.py: Renamed "Production Dependencies" to "Main Dependencies" for clarity and consistency. [1] [2]

Test updates:

• tests/test_html.py: Updated tests for _table_dependency_row to validate the new HTML structure and added detailed tests for _gather_status_class to ensure proper color mapping for different update types. [1] [2]

• Add unit tests for repository_url to verify correct selection from project_urls across different key orders and missing entries.

• [nitpick] Update the comment to use consistent capitalization (# Main Dependencies) to match the heading and project style.

• [nitpick] Consider adding type hints to calculate_update_type (e.g., -> Optional[str]) and annotating parameters for clearer API usage and better editor support.

• [nitpick] Indentation for this style assignment appears misaligned compared to surrounding elif blocks; align it with the other clauses to improve readability.
