P1: typed RPC bridge + FileSystemProvider + dual-panel local browsing
- shared/types + shared/rpc: full wire contract (Result envelope, no exceptions cross the bridge) - FileSystemProvider interface, LocalProvider, SessionRegistry with built-in 'local' - walk.ts: provider-generic recursive walk + removeRecursive - rpc-handlers wired into BrowserWindow; 10min request timeout for slow SFTP ops - Angular: RpcService (Electroview bridge + plain-browser guard), PanelsService with signals-based PanelState (sort/cursor/selection), FilePanel component with keyboard nav (arrows/Space/Enter/Backspace/Tab), path bar, toasts - verified: both panels listDir home over the bridge in the running app Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
