test fixes: dialog selector, closeAll scope, copy filter, runner ?v=3

* card-interactions.test.js: group delete tests used `.dialog-ok`
  (class selector) but the button has `id="dialog-ok"`. querySelector
  returned null, the click was skipped, the dialog stayed open and
  blocked every downstream test. Fixed to getElementById.
* runner.js closeAll(): added #dialog, #bucket-super-popover (remove),
  and #gitea-overlay to the cleanup list. A failed test that leaves any
  of these open no longer poisons the rest of the suite.
* runner.js copy handler: when there are failures or flaky tests, the
  "copy" button now builds the clipboard text from lastResults —
  only failed + flaky lines (suite name, test name, timing, error,
  original error for retried). When everything passed, copies the
  full output as before. lastResults is set in renderResults().
* bucket-context.test.js: move-left test used `[data-bucket]` to find
  user bucket tabs, which misses super-bucket tiles (they carry
  `data-bucket-super`). Changed to `[data-bucket-drag]` which is on
  both regular and super-bucket tiles but not on fixed filters.
* context-menu.test.js: make-ticket pre-fill assertion now polls up
  to 2s for the title input to be populated (async openCreateForm
  repo-fetch was racing against the immediate assertion).
* card-join.test.js: clickJoin sleep bumped from 400ms → 800ms.
  joinSelectedCards does 3+ serial API calls (fetch bodies, PATCH
  winner, N×DELETE losers, _reloadAll) which sometimes exceeded the
  old 400ms window on slow runs.
* Runner cache: RUNNER_V bumped from ?v=2 → ?v=3 in loader.js + all
  42 test files so the browser picks up the new runner.js content
  (copy handler, closeAll, retry progress bar) without a hard reload.

super-buckets: remember last selection per group

* buckets.js: module-scope lastSuperSelection Map tracks the last
  active member per super-bucket parent. Updated in renderBar()
  whenever activeBucket matches a group member. tileFor() uses it
  as a fallback when the user is on a different bucket — the tile
  shows the last-picked child's name and color instead of reverting
  to the parent. The dropdown popover also highlights the last
  selection when no member is currently active.

chore: bump version to 0.9.11
