Patch Changes

• Tab rename UX: clicking an already-active tab pill opens its properties
  popover (Notion-style); pressing Enter inside a single-line string input
  in any PropPanel dismisses the popover.

  UX research found users couldn't discover how to rename a tab — the pill
  itself had no rename affordance, and the only path was a hover-revealed
  chrome bar on the Tab body. Clicking the same pill twice now opens the
  Tab Properties popover with the Label input focused, so a user who clicks
  expecting to edit finds the rename surface on the very next click. The
  gear button gained a data-jsx-gear attribute so Tabs.tsx can address it
  without coupling to its i18n'd aria-label.

  Enter on a single-line string input now matches the form-submit contract
  every text input ships with — pressing Enter after typing acknowledges
  "I'm done" and closes the popover. PropPanel auto-saves on every
  keystroke, so Enter is acknowledgment, not commit; nothing about the
  data path changes. Both PropPanel's plain <Input> branch and
  SrcAutocomplete's empty-suggestion-list branch route through a new
  onDismiss callback that JsxComponentView wires to its popover close.
  CodeMirror code editors keep Enter as newline (multiline by design);
  SrcAutocomplete's existing "Enter picks the highlighted suggestion"
  contract takes priority when a suggestion is highlighted.
