What: Input context for fetching a combined news feed.

Inputs:

• limit: Maximum number of items per source.
• include_*: Source toggles.
• installed_filter: Optional installed-package set for scoping.
• installed_only: Whether to restrict advisories to installed packages.
• sort_mode: Sort order.
• seen_pkg_versions: Last-seen map for package updates.
• seen_aur_comments: Last-seen map for AUR comments.
• max_age_days: Optional maximum age in days for filtering items (enables early filtering).

Output:

• Mutable references updated in place alongside returned feed items.

Details:

• Hashers are generic to remain compatible with caller-supplied maps.
• max_age_days enables early date filtering during fetch to improve performance.
