[TraceParent] Turning off the setting still injects traceparent

[foxish]

I turn it on, then turn it off.

The extension says it's not injecting tracestate, but it is injecting it anyway.

I saw some errors using the dogfood version from current main reported on the extensions UI that may be related:

Yes I'm fixing that issue

This race condition occurs because multiple state updates are happening simultaneously. Currently, we have a single hook that updates the React state, which in turn triggers a local update. My initial refactor improved the code structure but didn’t resolve the underlying issue. To properly address this, I’m moving the hook into a context to ensure there's a single source of truth (SPOT) for managing the state.
