cargo build --release alone doesn't produce a working standalone binary in Tauri v2 — embedding the frontend vs. hitting devUrl at runtime is gated by the tauri/custom-protocol Cargo feature, not the debug/release profile. The scaffold never declared it, so even release builds tried to connect to localhost:1420. Added the standard default-on custom-protocol feature (cargo tauri dev strips it via --no-default-features for dev builds); a plain `cargo build --release --locked` in src/ now produces a real standalone binary with no dev-server dependency. Also fixes vite.config.js's file-watch ignore pattern, left stale by the src-tauri -> src rename: a bare "**/src/**" glob would have also matched frontend/src itself, so it's now an absolute path scoped to the Rust project dir specifically.
