v0.8.6

Hotfix release. Same app features as v0.8.5 (Detectorv2 v2.5, adaptive Live overlay, Viewer panels, grouped timeseries, Detectorv2-default extraction) — this corrects the release pipeline so the auto-updater manifest (latest.json) publishes.

Fixed

• The macOS updater-signature step searched a tripled bundle path (target/<triple>/release/bundle/macos) while the native build outputs to target/release/bundle/macos, which failed the deploy and skipped the latest.json publish in v0.8.5. Corrected.
