Summary of ChangesHello @rochaferraz, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request adds a new Python utility script that continuously monitors and displays detailed information about mDNS services on the local network. It is particularly useful for discovering Thread Border Routers but can be configured to scan for any mDNS service, providing real-time updates on their network addresses and associated properties.

Code Review
This pull request introduces a helpful Python script, mdns-browser.py, for scanning and displaying mDNS services on a local network. The script is well-documented and functional. My review includes a few suggestions to improve its robustness and maintainability. The most critical feedback is regarding a blocking call within the mDNS listener, which could lead to missed service announcements. I've also suggested refactoring the listener class for better clarity and removing an unused import. Overall, this is a great addition.

Code Review
This pull request introduces a helpful Python script for scanning mDNS services. The script is well-documented with a comprehensive header comment. My review focuses on improving its robustness, maintainability, and adherence to Python best practices. The most critical issue is a blocking call within an event callback, which could lead to missed service updates. I've also suggested using argparse for more robust command-line handling and improving code quality by using constants and type hints.

Code Review
This pull request introduces a helpful Python script, mdns-browser.py, for scanning mDNS services. The script is well-structured, leveraging threading and queues for non-blocking service discovery. My review focuses on enhancing the script's robustness and code quality. I've identified a significant race condition in the shutdown logic that could lead to unpredictable behavior, along with some medium-severity suggestions to improve code cleanliness and the consistency of the user-facing output.

Pull Request Overview
This PR adds a new Python script (mdns-browser.py) for continuously scanning and resolving mDNS services on the local network, with a default focus on Thread Border Router's _meshcop._udp.local. service.
Key changes:
- New terminal-based mDNS browser with real-time service discovery, updates, and removal notifications
- Multi-threaded architecture using a queue to handle service resolution asynchronously
- Support for custom service types via command-line arguments

Code Review
This pull request introduces a new mDNS browser script, enhances network diagnostic capabilities, and adds support for RLOC16 addresses. It also includes extensive formatting changes across the codebase and updates build scripts to use newer toolchains like LLVM 19. The functional changes are solid, especially the network diagnostics and RLOC16 support, which are well-tested. My feedback focuses on minor issues in the new script and a couple of corrections in the test suite.

Refactor mdns-browser.py to use a worker thread and a queue for service resolution, preventing blocking of the main event loop. - Correctly report host_ttl and other_ttl from ServiceInfo. - Add robust error handling for all service info fields using getattr. - Reintroduce proper TXT record parsing for binary data.

Code Review
This pull request introduces a new Python script, mdns-browser.py, designed to scan for and display information about mDNS services on a local network. The script is well-structured, utilizing a separate worker thread for resolving service details to avoid blocking the main mDNS listener, and it includes proper handling for graceful shutdown. My review provides a few suggestions to enhance the script's quality, including correcting a typo in the documentation's usage example, renaming a function parameter to avoid shadowing a Python built-in, and refactoring a piece of duplicated code into a helper function to improve overall maintainability.

Code Review
This pull request introduces a well-structured and useful Python script for browsing mDNS services. The code is clear, well-documented, and correctly handles asynchronous operations and graceful shutdown. My feedback includes a few suggestions to enhance maintainability and align with common Python practices, such as simplifying the worker thread's logic and improving how command-line arguments are handled.

Introduces IPv6 address support to the fake border agent script and updates the mDNS browser integration test to verify the discovery of both IPv4 and IPv6 addresses. This change - Adds an constant to and includes it in the addresses. - Modifies to check for the presence of the IPv6 address in the mDNS browser output.

Agree with AI suggestions. Extracted TXT decode logic into a helper function, simplified the worker thread sentinel logic, added timeout to zeroconf.get_service_info, and removed unused socket import. Pushed fixes to PR.
