UDPStreamer: - Add PublishingMode = "Strict" | "Auto" config parameter - Add MinRefreshRate (Hz) for Auto mode; uses HRT phase-locked tick counting to rate-limit sends without accumulation buffers - Fix high-frequency integration test configs to use newline-separated key-value pairs (MARTe2 StandardParser does not treat ';' as delimiter) - Add 3 new unit tests (AutoMode_Valid, AutoMode_MissingRefreshRate, UnknownPublishingMode); all 33 tests passing WebUI hub: - Skip ring-buffer LTTB writes when zoom has not been accessed in 10 s, reducing idle CPU usage - Use unsafe float64→bytes reinterpretation to eliminate per-element encoding overhead in the hot broadcast path Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
