Summary of Changes

This PR incorporates the results of a comprehensive technical audit, bug fixing, optimization, and agent infrastructure deployment for HyperBoost (io.github.mrquster.hyperboost).

1. DSP & Audio Engine

• Limiter Continuity: Fixed $C^1$ jump of ~3,700 amplitude units at the knee boundary ($0.75 \times \text{threshold}$) in SoftwarePcmDspProcessor and AudioBoosterService soft-knee tanh limiters.
• Zero-Allocation PCM Loop: Eliminated 48,000 Pair<Double, Double> heap allocations per second in PCM audio capture loop via zero-allocation processStereoSampleDirect.
• Audio Lifecycle: Added missing audioManager.requestAudioFocus(req) call in AudioBoosterService and registered AudioDeviceCallback with clean unregistration on service destroy.

2. UI & Navigation

• Lens Tab Bar: Connected freeLensDragEnabled setting to GlassLensTabBar, ensuring 100% reliable tab switching on normal tap without accidental drag interception.
• Deprecated Icons: Replaced deprecated Compose icons (FactCheck, OpenInNew) with AutoMirrored counterparts.
• Condition Optimization: Cleaned up redundant condition check in tab bar backdrop blur.

3. Localization (i18n)

• Eliminated hardcoded strings in Glance Widget, Home, Island JSON Builder, and System screens.
• Achieved 100% key parity between English (values/strings.xml) and Russian (values-ru/strings.xml) resources (verified via automated unit test).

4. Agent Infrastructure & Documentation

• Added core agent rules (AGENTS.md, .agent/rules/), 10 specialized skills, 7 workflows, and 2 sub-agent roles.
• Restored complete release instructions in docs/RELEASING.md, updated CHANGELOG.md, and cleaned README.ru.md.
• Comprehensive technical report: docs/agent/AUDIT_REPORT.md.

Verification

• ./gradlew test passes 100% (8 unit tests).
• ./gradlew lintDebug passes.
• ./gradlew assembleDebug and ./gradlew assembleRelease (R8 size: 4.1 MB) succeed without errors.
