Extracts duplicated platform integration code from ChronoMind + LysnrAI into a single Swift Package. Eliminates ~1,100+ lines of copied code per product app. Components: - BLPlatformConfig — product-specific configuration (productId, baseURL, bundleId) - BLPlatformClient — generic HTTP client with auth injection, x-request-id, timeout - BLKeychain — Keychain CRUD for secure token storage - BLTelemetryClient — telemetry queue + batch flush (matches @bytelyst/telemetry-client) - BLAuthClient — full auth operations (matches @bytelyst/auth-client) - BLFeatureFlagClient — feature flag polling from platform-service /flags/poll - BLSyncEngine — generic offline-first sync with delta pull + batch push Platforms: iOS 17+, watchOS 10+, macOS 14+
