This pull request introduces a stale-while-revalidate (SWR) cache for GraphQL responses, adds a test coverage summary comment to pull requests, and improves configurability and efficiency of forum data fetching. It also refines several naming and configuration conventions for consistency. The most important changes are grouped and summarized below:

Caching and Data Fetching Improvements:

• Added a robust SWR cache in src/lib/cache.ts for GraphQL data, with user-scoping, versioning, TTL, and quota management. This enables instant page loads from localStorage and background revalidation, configurable via the new cache section in forum.config.ts. [1] [2] [3]
• Refactored forum data fetching in src/lib/github/api.ts to load categories, user permissions, and the first page of discussions in a single request (getOverview), reducing load time and redundant requests. [1] [2]

Configuration and Feature Flags:

• Added listExcerpts to the content config, allowing forums to disable body excerpts in discussion lists for smaller payloads; updated related logic and documentation. (Fc493ad4L91R91, [1] [2]
• Introduced a cache config section with enabled and ttlSeconds options for controlling the new SWR cache. [1] [2] [3]

CI and Developer Experience:

• Updated the GitHub Actions workflow to comment a formatted test coverage table on pull requests, improving visibility into test quality. [1] [2]

Consistency and Naming:

• Standardized project-specific prefixes from gf: to dk: across theme storage, article markers, and sign-in token fields for clarity and branding consistency. [1] [2] [3] [4]

Component and API Improvements:

• Improved the reply posting flow in CommentCard.svelte by returning the created reply object to the parent component, enabling immediate UI updates. [1] [2] [3]
