Summary by CodeRabbit
WalkthroughRefactor the comment and thread output logic in the main Rust source file by introducing generic writer-based functions to modularise and unify output generation. Update documentation for Rust-specific guidance in AGENTS.md by splitting a line for clarity. Add a test to verify correct diff output in threads. Changes

Hey @leynos - I've reviewed your changes and found some issues that need to be addressed.
- Avoid silently discarding errors by calling
.ok()on print_thread in run_pr—either propagate the Result or at least log failures instead of ignoring them. - Consider making print_comment_body return a Result (like print_comment) so that both printing helpers have consistent signatures and error handling.
- You can simplify the default-author logic with
comment.author.as_deref().unwrap_or("")instead ofas_ref().unwrap_or(&"".into()).

1-1: Excellent addition of module documentation.This properly addresses the previous review comment and follows the coding guidelines requirement for module-level documentation.
687-688: Perfect implementation of the thread-based printing logic.This change correctly shifts from comment-by-comment iteration to thread-based printing, achieving the PR objective of showing diffs once per thread. The updated error message accurately reflects the new behaviour.

Where a function is too long, extract meaningfully named helper functions adhering to separation of concerns and CQRS.
Where a function has too many parameters, group related parameters in meaningfully named structs.
Where a function is returning a large error consider using Arc to reduce the amount of data returned.
Write unit and behavioural tests for new functionality. Run both before and after making any change.
