Rust SSH service: russh async client, DashMap session registry,
TOFU host key verification, CWD tracking via separate exec channel
(never touches terminal stream), base64 event emission for terminal
I/O. 52/52 tests passing.
Vue 3 frontend: ported from Wails v3 to Tauri v2 — useTerminal
composable with streaming TextDecoder + rAF batching, session store
with multi-connection support, connection store/tree, sidebar, tab
bar, status bar, keyboard shortcuts. All Wails imports replaced
with Tauri API equivalents.
