Guilhem Lemouel d5c6fac3ad fix(picker): stop self-feeding fetch effect that OOM'd the tab
The drill picker's $effect watched `scope` and called `ensureLoaded`
on every change. `ensureLoaded` reads `loaded[kind]` synchronously
(to decide whether to show a spinner), so the effect ended up
subscribed to the very signal it fills. Each fetch result wrote
`loaded[kind] = items`; Svelte 5's $state proxy notifies on every
property set even when the reference is unchanged from cache, which
refired the effect, which called `ensureLoaded` again, which awaited
the cached fetch, which wrote `loaded[kind]` again... runaway loop.

In `/scripts/edit/...` the picker's lifecycle stabilised quickly
enough to mask the loop, but in a session pane (multiple warm
sessions, picker kept alive by the surrounding state) the cycle
spun freely — 29.8 million iterations in <100 ms during testing,
enough to OOM Firefox / kill the Chromium tab.

Two changes:

- Replace the scope-watching $effect with an explicit `setScope()`
  helper called from `drill()`, `goUp()`, and `onMount`. Fetch is
  now a callback reaction to user navigation, never a reactive
  consequence of one. No closed feedback cycle is possible.

- Untrack the `loaded[kind]` read inside `ensureLoaded`. The search
  $effect (which loads every kind on first keystroke) is still a
  reactive caller; the untrack stops it from subscribing to the
  signal `ensureLoaded` fills, so the same loop can't form there.
