m/h: does still work in our CDN bundles where we mangle private _-prefixed names?
l: Not particularly a fan of extracting this to a function and then accessing private members. Is there a reason for this over adding a private method to the Client class?

alternatively, could we keep the weight property (+whatever else) as variables within the closure of setupWeightBasedFlushing?

yeah using closure variables is way nicer. Lemme refactor.

…ry#17901) We've seen some cases where our browser logs are hitting size limits. I suspect this is because we don't have any robust size tracking mechanisms in the browser sdk. <img width="1251" height="513" alt="image" src="https://github.com/user-attachments/assets/2364b984-2b53-4c6a-89e5-0a0e20fa3246" /> This refactors our log flushing mechanisms in the SDK to unify everything between the browser client and server runtime client. This also means the browser SDK gets a weight tracking mechanism for buffering, which should help with making sure we don't run into size issues with logs. Given metrics has the same issue, I included it in this refactor.
