Nova 1.1.0 performance hardening

[papi-ux]

Summary

• Add structured stream performance samples and route them into NovaHUD while keeping the legacy overlay text path intact.
• Replace the HUD sparkline sample path with a fixed primitive buffer and expand Baseline Profile journeys for library detail, settings, and launch-adjacent Compose surfaces.
• Harden Polaris-backed lock/reconnect behavior by requiring success: true for unlock responses, hiding raw idle progress labels, and retrying stale saved host ports on the default Polaris HTTP port.
• Document the JNI bridge measurement gate and prepare the 1.1.0 release metadata, changelog, README, and Retroid 6 evidence.

Validation

• ./gradlew -PnovaAbis=x86_64 testNonRoot_gameDebugUnitTest --console=plain
• ./gradlew assembleNonRoot_gameRelease --console=plain
• JAVA_HOME=/usr/lib/jvm/java-25-openjdk ANDROID_HOME=/home/papi/Android/Sdk ./gradlew :app:testDebugUnitTest --tests com.papi.nova.computers.KotlinComputerServiceMigrationTest --tests com.papi.nova.api.PolarisApiClientParsingTest --tests com.papi.nova.ui.NovaStreamOverlayUiStateTest --console=plain
• JAVA_HOME=/usr/lib/jvm/java-25-openjdk ANDROID_HOME=/home/papi/Android/Sdk ANDROID_SERIAL=adb-24c12bdd-gitDJe._adb-tls-connect._tcp ./gradlew :app:installRootDebug --console=plain
• JAVA_HOME=/usr/lib/jvm/java-25-openjdk ANDROID_HOME=/home/papi/Android/Sdk ANDROID_SERIAL=adb-24c12bdd-gitDJe._adb-tls-connect._tcp ./gradlew :app:installNonRoot_gameDebug --console=plain
• git diff --check
• bash scripts/check-public-docs.sh
• Retroid Pocket 6 wireless ADB smoke: installed ARM64 debug APK, repaired Trusted Pair, opened Polaris library, launched/resumed Steam Big Picture, enabled NovaHUD from Command Center, disconnected back to Nova Library.
• Retroid stale-port smoke: forced com.papi.nova.debug saved host DB from 10.0.0.232:47989 to 10.0.0.232:49000, launched Nova 1.1.0, confirmed it rewrote the saved local address back to 10.0.0.232:47989 and restored Polaris TLS readiness.
• Retroid log checks: /tmp/nova-1.1.0-retroid-stream.log and /tmp/nova-1.1.0-retroid-crash.log had no Nova fatal exception or ANR matches.

Notes

• The Retroid launcher intercepted ADB-injected Guide/Mode chords, so the automated HUD pass used Nova's Back-key Command Center path instead of Guide+Y.
• The JNI annotation work is intentionally documentation-gated until profiling proves a concrete JNI call is safe for @FastNative or @CriticalNative.
