feedback7 R22-E2EFIX: an Esc pressed the moment the 自选 picker opens closes it (its listener comes with the picker's commit); golden: unchanged

The 0.2.2 full browser pass failed diy.e2e 「5阶 / 6阶 slots: Esc cancels the picker…」 (GitHub #284's test) at the
wait for the picker to close after Esc. The picker does open on a real click (the suite's other three tests open it
with real mouse clicks; all green). The cause is a race in the UI: DiyPicker attached its keydown listener in a plain
effect, which runs a frame after the picker is in the DOM, while the 干员调配 overlay's own Esc handler skips Esc as soon
as `.diy-pick` exists — an Esc pressed in between was swallowed and the picker stayed open. Reproduced every time by
dispatching Esc right after the picker renders; on a loaded machine the test's own Esc hit the window. Now a layout
effect: the listener is live in the picker's first commit.

- Test: diy.e2e (the Esc test) adds that immediate Esc — it fails on the parent with the full pass's error and passes
  now; the whole suite 4/4 (SP_E2E=1), test/ui unit tests 699 pass.
