feat(release): code quality & performance overhaul v1.2.0

- Performance: optimized React rendering in DevicePage/DisplayPage using useMemo/useCallback
- Stability: fixed 50+ instances of any types and empty catch blocks to prevent silent failures
- Storage: fixed Set serialization issues and converted sync file writes to async debounced writes
- CI: fixed GitHub Actions macOS build failure by disabling mandatory signing in CI environment
- Quality: extracted hardcoded parameters like polling intervals and log retention to constants

 ## [Unreleased]
 
+## [1.2.0] - 2026-01-15
+
+### Fixed
+
+- Fixed several empty catch blocks across Electron main process for better error traceability
+- Fixed Set serialization issues in device storage affecting state persistence
+- Fixed TypeError in DeviceCard/DevicePage by migrating from Set.has() to Array.includes()
+- Fixed GitHub Actions build failure on macOS by disabling mandatory code signing requirements
+- Improved error handling by replacing `any` types with `unknown` and adding proper type checks
+
+### Changed
+
+- Converted synchronous file writes to asynchronous debounced writes to prevent blocking the main process
+- Optimized device polling interval (increased from 5s to 10s) to reduce CPU and network usage
+- Extracted hardcoded configuration values (polling intervals, log retention) into maintainable constants
+
+### Performance
+
+- Optimized React rendering in DevicePage using useMemo for derived device lists
+- Wrapped event handlers in useCallback to prevent unnecessary child component re-renders
+- Cached scrcpy command preview calculation using useMemo
