 * Adds a key-value property to the current session.

 * Session properties are searchable in the Embrace dashboard and can be used to
 * filter and categorize sessions.
 *
 * @param key - The property name
 * @param value - The property value
 * @param permanent - If `true`, the property persists across sessions until explicitly removed.
 *   If `false`, the property is cleared when the session ends.
 * @returns A promise that resolves to `true` if the property was successfully added, `false` otherwise
 *
 * @example
 * ```typescript
 * import { addSessionProperty } from '@embrace-io/react-native';
 *
 * // Temporary property (cleared at session end)
 * addSessionProperty('launch_type', 'push_notification', false);
 *
 * // Permanent property (persists across sessions)
 * addSessionProperty('subscription_tier', 'premium', true);

 * Retrieves the ID of the currently active session.

 * @remarks
 * If called inside an `AppState` change listener, the session may be in the process
 * of ending. Consider adding a delay or calling at another point in the lifecycle
 * to ensure you get the session ID you expect.

 * @example
 * ```typescript
 * import { getCurrentSessionId } from '@embrace-io/react-native';

 * It only changes after a full app restart.
 *
 * @returns A promise that resolves to one of:
 *   - `"INVALID"` - SDK was not started when this was called
 *   - `"CRASH"` - The previous app instance ended in a crash
 *   - `"CLEAN_EXIT"` - The previous app instance exited cleanly
