fix(browser): Skip INP interaction listeners when span streaming is enabled

logaretm · claude · logaretm · commit 739fcf457266 · 2026-04-02T10:36:20.000-04:00
The streamed INP path does not use INTERACTIONS_SPAN_MAP or
ELEMENT_NAME_TIMESTAMP_MAP, so registering the listeners is unnecessary overhead.
