+Apply --app-name to VS Code web page titles
+
+VS Code's `${appName}` title variable comes from `productService.nameLong` in the
+web client. code-server already injects per-request product configuration into
+VS Code's web bootstrap, so set `nameShort`/`nameLong` from the existing
+`--app-name` CLI arg there.
+
+This keeps the patch minimal and makes browser tab titles honor `--app-name`
+without changing unrelated product metadata.
