Graywolf RXT test build d3114df4

RXT test build based on Graywolf 0.14.14, commit d3114df.

Changes

• Station map popups and pinned windows now show Receiver DX from measured RXT links, calculated separately for each receiver. The card includes distance, true bearing, RSSI, SNR, frequency offset, reception time and distinct direct transmitters observed over 30 minutes.
• Relayed receptions use the actual radio transmitter, not the original packet source. DX / Status distance, window and ignored-station settings also apply to receiver DX.
• Stations advertising <IGATE,...> bulletins get a separate iGate report card with their announced counters, DX and reception time. Later position beacons preserve this report.

Setup and limits
Restart Graywolf and refresh the browser after installing. Existing configured JSON streams supply receiver DX automatically; no firmware change is required. Both endpoint positions must be known. Receiver windows start empty after restart and fill with new receptions.
RXT observations may cover only part of a receiver's traffic. Direct-station counts are observed counts; MSG_CNT, LOC_CNT and RF_CNT are not inferred. Receiver DX is passive and does not transmit reports. Legacy /rxt.json polling remains overlay-only.
Advertised iGate reports survive restart when station-history persistence is enabled; wait for the next bulletin after installing.

Validation
Receiver DX was verified on F4MLV-10 with F4INI-10 at 93.8 km. Go race tests for the affected components and station endpoints, 585 Web tests, browser checks and documentation checks passed.

RXT test pre-release. No OCI images are published; GHCR latest is unchanged. Windows is supplied as a ZIP archive without an installer. macOS ARM binaries are cross-compiled and are not runtime-tested on Apple Silicon in this build.
