Thank you for this contribution. The changes to handle SPA navigation and prevent race conditions are a great improvement. I've identified a critical issue related to the initialization of the MutationObserver and a few areas where the code can be made more maintainable by adhering to the repository's style guide.
Specifically, my review focuses on:

Thank you for this contribution. The changes to handle SPA navigation and prevent race conditions are a great improvement. I've identified a critical resource leak with the MutationObserver and a high-risk implementation detail regarding page load timing. Addressing these will significantly improve the extension's robustness and performance.
My review is based on the repository's style guide, focusing on writing clean, bug-free, and maintainable code (Repo Style Guide, Lines 4, 13, 15).

This pull request does a great job of improving the extension's robustness, especially for SPA navigation on GitHub. The changes align well with the repository's style guide, particularly regarding the use of constants for magic values (Rule #10) and handling complex asynchronous UI updates. I've identified a couple of issues related to resource management in the new SPA handling logic that could lead to memory leaks and performance degradation over time. My comments below provide details and suggestions for fixing them.

I've reviewed your pull request. The changes look solid and effectively address the issue of badge display on SPA navigations. The use of debouncing, a processing flag, and SPA event listeners are all great additions.
I have a couple of suggestions, mostly related to improving code clarity and maintainability by reducing duplication and refining logic flow. These are based on the repository's style guide, particularly rules about conciseness (#4), avoiding duplication (#15), and writing clean, maintainable code (#13).

I've reviewed your pull request and I'm impressed with the improvements to handle SPA navigation. The use of debouncing, a processing flag, and event listeners for turbo:load and pjax:end are all great additions. I have a few suggestions to further improve the correctness and maintainability of the code. My feedback is focused on ensuring the MutationObserver is managed correctly across SPA navigations and adhering to the project's coding style for variable declarations. Please see my detailed comments below.

This is a great pull request that significantly improves the robustness of the extension, especially with handling SPA navigation on GitHub. The use of debouncing, a processing flag, and polling for elements are all excellent additions.
I've found a couple of areas for improvement:
- Code Style: There's a minor violation of the repository's style guide regarding the alphabetical sorting of constants.
- Robustness: There's a potential edge case with a lingering timer after SPA navigation that could be addressed for improved stability.
I've left specific suggestions on the relevant lines of code. Keep up the great work!

Overall, the changes in this pull request are well-implemented and effectively address the issue of badge display on SPA navigation. The use of debouncing, a processing flag, and event listeners for turbo:load and pjax:end demonstrates a solid understanding of the complexities of developing a content script for a modern web application like GitHub.
The code adheres well to the provided style guide. My review includes a couple of suggestions for minor refactoring to further improve modularity and code reuse, in line with Rule #7 (Separation of concerns) and Rule #15 (Code reuse and modularization) from the repository's style guide. These are not critical but would enhance the long-term maintainability of the code.

This is a great pull request that significantly improves the extension's robustness, especially with the handling of Single-Page Application (SPA) navigation on GitHub. The code is well-structured, and the logic for debouncing, preventing concurrent processing, and polling for DOM elements is solid.
I've reviewed your changes against the repository's style guide and found that the code adheres to it well. Specifically, I noticed and appreciated:
- Use of Constants: Magic numbers and strings have been correctly extracted into constants (Style Guide, line 10).
- Separation of Concerns: The new functions like
cleanupPollingTimers,cleanupObserver, andhandleSPARoutingcreate a clean separation of logic (Style Guide, line 7). - TypeScript Best Practices: The code correctly uses
typeoverinterfaceand arrow functions, as per the guidelines (Style Guide, lines 22-23).
I have one high-severity comment regarding a potential resource leak during SPA navigation. Otherwise, the changes are excellent.
- Expand content script to load on all GitHub repository pages - Add debouncing (500ms) to prevent infinite MutationObserver loops - Implement processing flag to prevent concurrent API calls - Add turbo:load and pjax:end event listeners for SPA routing - Wait for DOMContentLoaded when page is still loading fix #18

This pull request effectively addresses the issue of badge display on SPA navigation by expanding the content script's scope and implementing robust handling for both initial page loads and dynamic content changes via turbo:load and pjax:end events. The introduction of debouncing for the MutationObserver and a processing flag for API calls are excellent improvements for performance and stability.
The code adheres well to the provided repository style guide, particularly in its use of constants, arrow functions, and early returns. My review includes one suggestion aimed at further improving long-term maintainability by separating concerns, in line with the style guide's principles.
