This change adds JSDoc-style comments to several functions and classes across the codebase to improve readability and maintainability.
Comments were added to:
- `src/SEQTA.ts`: Explained the `init()` function.
- `src/seqta/utils/waitForElm.ts`: Detailed the `waitForElm()` function, its parameters, and behavior.
- `src/seqta/utils/stringToHTML.ts`: Clarified the `stringToHTML()` function, including its sanitization and styling features.
- `src/seqta/utils/delay.ts`: Added a brief explanation for the `delay()` utility.
- `src/seqta/utils/mutex.ts`: Documented the `Mutex` class and its `acquire` method (renamed from `lock`), explaining its asynchronous locking mechanism and the role of the returned unlock function.
