enricobuehlerandClaude Opus 5 7536f7319a fix(gamestream): a software-encode host must advertise H.264 only
`base_codec_mode_support` fell through to the static superset (H.264|HEVC|AV1) on a
GPU-less host, so Moonlight negotiated HEVC or AV1 and the session then died at
encoder open with "the software encoder emits H.264 only" — openh264 encodes nothing
else. The native plane's twin of this function, `pf_encode::Codec::host_wire_caps`,
has gated on exactly this since it was written; this one never did.

Deliberately a local gate rather than delegating wholesale to `host_wire_caps()`.
Delegation is the drift-proof shape and was the first design, but on Windows it
re-runs the DXGI adapter enumeration several times per `/serverinfo` GET — the probe
helpers each sample it uncached — and this endpoint is polled by every client. The
software case is a plain config read, so it costs nothing here.

Recorded in a comment rather than fixed: the static `MaxLumaPixelsHEVC` in the
serverinfo XML still advertises an HEVC limit even when the mask now drops HEVC.
Harmless (Moonlight gates capability on the mask, not the limit) but it is a second,
now-inconsistent advertisement.
