* test(app/e2e): add picker keyboard-interaction tests (Cluster G8)
Cover branch-picker keyboard contract: open via Space, navigate with
ArrowDown/ArrowUp, select with Enter, close with Escape.
Adds six helpers to helpers/new-workspace.ts:
openBranchPicker, selectPickerOptionByKeyboard, closeBranchPicker,
expectPickerOpen, expectPickerClosed, expectPickerSelected.
Also moves delayBrowserAgentCreatedStatus and its private helpers out of
new-workspace.spec.ts into the helpers module where they belong.
* fix(app/e2e): address picker keyboard test review feedback
- Add { timeout: 30_000 } to expectPickerClosed (FadeOut animation safety)
- Simplify selectPickerOptionByKeyboard: ArrowDown → Enter (remove redundant ArrowUp)
- Migrate expectStartingRefPickerTriggerPr trigger selector from testID to ARIA role
* fix(app/e2e): fix picker keyboard test — open via click not Space
RN Web Pressable renders as <div role="button"> which does not fire
onPress from a programmatic Space key event. Switch openBranchPicker
to trigger.click() so the picker reliably opens in CI headless Chrome.
Keyboard behaviour (ArrowDown + Enter, Escape) is still exercised by
selectPickerOptionByKeyboard and closeBranchPicker respectively.
