Issue #176: the original Context.report_progress treated token 0 as "no token" and

silently dropped progress. Context now delegates unconditionally to
|

ServerSession.report_progress (which calls DispatchContext.progress, whose JSONRPC

implementation gates on `is None`, not truthiness), so a request whose meta carries
|

a 0-valued token still emits all three reports.
