Expand description

Inspect only a client’s mandatory H2 prefix without emitting server bytes.

A different protocol returns None and rewinds every consumed byte. An H2 client must send its initial SETTINGS before waiting for server output, so this never waits for request HEADERS or a WINDOW_UPDATE. The caller owns the overall deadline. Native framing/settings validation and bounded observation are reused here.
