- Add AudioTabListener to track audio playback in inactive tabs - Track tab state changes during playback to record only background time - Prevent double counting by skipping active tab segments - Add onTabRemoved wrapper to chrome tab API When users play media (e.g., YouTube) and switch to another tab, the audio continues playing in the background. This feature tracks that background playback time separately from active tab time tracked by content scripts.

@mrfragger hi, thanks for your PR. there may be not accurate on Chrome and Edge. since they all don't promise the service worker always alive, which causes all audio states loss if background script is unloaded randomly. so I think it's better to store the audio state of each tab in the contentscript and report them with payload of tracking event, while I don't find any API to do that. but we can still monitor tabs by extension API, and send them to the tab's contentscript |
- Store audio playback state in chrome.storage.local every 5 seconds - Restore state on service worker restart - Ensures tracking survives service worker termination in Manifest V3 browsers - Minimal overhead: only persists when tabs are actively playing audio Tested on Chrome/Iron with manual service worker termination.

Adds audio tracking for background tabs using the browser's
tab.audibleAPI to track media playback when tabs are inactive. Currently, the extension only tracks time when users actively interact with a tab (via content scripts). When users play media (like YouTube videos) and switch to another tab, that background playback time is not tracked.
