Refactor extensions to async/sync API

Redesign extension handling to support explicit async/sync execution. helpers/extension.py rewrites the extensible decorator, adds call_extensions_async / call_extensions_sync, and a helper to gather extension classes; caching flag adjusted. Updated call sites across the codebase (agent, APIs, plugins, tools, settings, extensions) to use extension.extensible and the new call_extensions_async/sync API, and converted several extension handlers from async to sync. Also small frontend tweaks (use globalThis.runtimeInfo) and minor import updates (csrf_protect in run_ui). This centralizes extension discovery/execution and avoids previously scattered asyncio.run usage.
