* Align NES recording bookmark with prompt-build snapshot
The recording bookmark used as requestTime in alternative-action telemetry
was created at provider entry time, but document/selection state used to
build the prompt is snapshotted later in _executeNewNextEditRequest. This
caused replay tools to miss selection-change events that were actually
reflected in the prompt.
* Plumb refreshed bookmark into telemetry builder
Addresses Copilot review: LlmNESTelemetryBuilder snapshots the bookmark
in its constructor and reads _requestBookmark.timeMs later, so updating
only logContext.recordingBookmark left telemetry requestTime unchanged.
Add a setter and call it from _executeNewNextEditRequest.
