v0.9.75

ShadowBroker v0.9.75 is refreshed as a same-version micro-update for the current public channel. This rebuild aligns the release tag, Windows installers, source ZIP, checksums, and release manifest with the latest runtime hardening and telemetry fixes.

## Highlights

- Tightened Wormhole/Infonet startup behavior so node status refreshes faster and retry/offline states are clearer during bootstrap.
- Added Tor/onion runtime wiring and cleaner seed-node configuration hooks for the obfuscated Infonet path.
- Improved Docker/local runtime configuration around node bootstrap and relay defaults.
- Updated tracked-aircraft emissions so selected aircraft can use observed trail history for cumulative fuel and CO2 estimates instead of showing only a rate.
- Preserved selected-only aircraft and vessel trail behavior so trails appear on demand instead of cluttering the map globally.

## Installers and Packages

- `ShadowBroker_0.9.75_x64-setup.exe` - Windows NSIS installer
- `ShadowBroker_0.9.75_x64_en-US.msi` - Windows MSI installer
- `ShadowBroker_v0.9.75.zip` - clean source package generated from the release tag
- `SHA256SUMS.txt` and `release-manifest.json` - verification metadata for the uploaded assets

## Notes

- This is an unsigned public Windows build. SmartScreen may warn until production code signing is added.
- API keys, local env files, operator secrets, runtime caches, and private node data are not included in the release assets.
- This release keeps the `v0.9.75` version number because it is a micro-refresh of the same channel, not a feature-version jump.
