Introduces opt-in file transfer capabilities and import/export message payloads for the file system plugin protocol. Adds raw base64 read/write support for Expo legacy, Expo modern, and RNFS adapters, including path existence checks used by overwrite handling. Also updates the public SDK exports, optional module typings, no-op adapter, and provider tests for transfer capability resolution and adapter behavior.
Adds fs:export-file and fs:import-file handlers on the React Native side. The handlers enforce the opt-in fileTransfer capabilities, resolve the active filesystem adapter, validate that paths stay inside configured roots, reject path traversal, and prevent importing over existing files unless overwrite is explicitly requested. Export reads files as base64 through the adapter and import writes base64 data back into the selected directory, returning structured result events for the panel to consume.
Adds panel-side request helpers for fs:export-file and fs:import-file, plus navigation state for the runtime-advertised file transfer capabilities. Adds browser utilities for reading selected files as base64 and downloading base64 responses as files. Wires the file system panel to import a single file into the current directory, ask before overwriting existing files, reload after successful writes, and surface transfer errors alongside existing filesystem errors. Adds an export action to the detail panel for selected files when export is enabled by the runtime.
Documents the opt-in file transfer capability for the file system plugin, including import/export setup for Expo and RNFS adapters. Calls out that transfer is disabled by default, supports single files only, imports into the currently viewed directory, and prompts before overwriting an existing file. Enables import/export in the playground app so the workflow can be exercised while developing the plugin.
