fix(CLI-37,CLI-38): make status/HRESULT reply validation conformant across all five clients

Browse Source 
One cross-client conformance pass; also closes first-cycle CLI-08.

CLI-37: an MxStatusProxy entry is a failure iff `category !=
MX_STATUS_CATEGORY_OK`. The proto contract has always said so — `success` is
the raw 16-bit COM member carried verbatim for diagnostics, not a boolean — but
four clients branched on `success` alone and .NET required both, so the same
gateway reply produced opposite verdicts per language. An absent entry stays
success; a present entry with an UNSPECIFIED category is a failure, because the
worker always maps a category and an unmapped one is not proven OK.

CLI-38: a reply fails on HRESULT iff `hresult` is present and negative, so
positive COM success codes such as S_FALSE (1) pass. .NET/Go/Java used `!= 0`,
which errored on a parity-preserving S_FALSE that Python and Rust accepted.
This makes the existing ClientLibrariesDesign.md claim true rather than
rewriting the doc to describe the divergence.

Four shared fixtures pin both rules cross-client, and each language suite also
carries a table test for the two edges a fixture cannot express (absent entry,
UNSPECIFIED category). A Java test fake that built a status with a bare
`setSuccess(1)` and no category is fixed — under the category rule that reply
was never a success.
