Remove dist directory and streamline build artifacts.

- Deleted `index.css`, `index.js`, and `index.html` from `app/web/dist/`.
- Cleared unused build artifacts to maintain a lean repository structure.

+# Build the embedded web UI and then install the Go binary.
+#
+# This script will:
+#  - Build the React app in app/web to app/web/dist using Bun (preferred),
+#    or fall back to npm/yarn/pnpm if Bun isn't available.
+#  - Run `go install` from the repository root so the binary picks up the new
+#    embedded assets.
+#
+# Usage:
+#   ./scripts/update-embedded-web.sh
+#
+# Requirements:
+#  - Go 1.18+ installed (for `go install` and go:embed support)
+#  - Bun (https://bun.sh) recommended; alternatively Node.js with npm/yarn/pnpm
