dioxus-dnd 4.0.0-alpha.1

Breaking changes

• Move the Dioxus public types from 0.7 to 0.8.0-alpha.1. Dioxus and
  Dioxus Desktop are pinned exactly to the published alpha.1 packages;
  later alphas have incompatible APIs. Existing 0.7 applications should
  remain on dioxus-dnd 3.x. The renderer-neutral dependency keeps
  default-features = false and its minimal, document, and mounted
  features.
• Raise the minimum supported Rust version from 1.85 to 1.88. The
  published Dioxus alpha uses let-chains, including in the minimal graph.

Migration fixes

• Close every forwarded style fragment with ; before the component's own
  declarations follow it, so a caller's style: "color: blue" no longer
  runs into touch-action and breaks both.

• Require web-sys 0.3.98 or a later 0.3 release (the floor Dioxus Web
  alpha.1 pulls), so cargo unifies on the app's single web-sys and
  mounted-element downcasts match; apps on a newer web-sys still build. Enable Location in the web
  feature so minimal downstream document/history builds compile without
  relying on this crate's dev-dependency features.

• Generate file-picker input IDs from a VDOM-root allocator instead of
  accessing ScopeId's numeric field, which is private at the supported
  Dioxus git revision. IDs remain stable during an instance's lifetime and
  start from the same sequence for independent SSR/client renders.

• Upgrade Dioxus SSR, the gallery's Dioxus i18n integration, both standalone
  desktop examples, and all three lockfiles to the matching alpha graph.

• Update installation/version guidance and replace obsolete 0.7-specific
  scroll-observation notes with the renderer-neutral sampling behavior.

• Keep automatic sortable group IDs checked and atomic using a compare-exchange
  loop, avoiding Rust 1.99's deprecated fetch_update without raising the MSRV.

• Refresh the transitive Rustls dependency in all three lockfiles to pick
  up its security fixes, and recognize xxhash-rust's permissive Boost license
  in the dependency policy.

• Make additive-selection browser regressions use Ctrl on Windows/Linux
  and Cmd on macOS, avoiding native Control-click context menus.

• Use the alpha.1 CLI in CI and gallery deployment, disable hot-patching in
  browser regressions and DWARF output in production gallery builds, and
  wait for the fixture build before starting browser tests. Test Rust 1.88
  and check a scratch downstream consumer against Dioxus git revision
  f9519967a6fb3e85bf3c1a2e2bf816a85033f752, and accept prerelease tags
  without marking alpha GitHub releases as latest.

The additions and fixes below were developed on dev after 3.1.0 and are
included in this release.

Added

• Keyed board moves. try_apply_move locates the moved item in its
  source column by key instead of trusting the event's index, adjusts
  same-column forward inserts from the index it actually found, and returns
  ApplyMoveError::SourceNotFound without touching the board when the drop
  is stale. apply_move keeps its index-based behavior and now documents
  that a column reordered under the drag makes it remove the wrong item.
• DropEffects set operators. &, &=, ! (the complement within
  STANDARD), From<DropEffect>, and FromIterator<DropEffect>.

Deprecated

• The payload-only registry lookups acceptable, step_zone,
  step_sibling, children_of, and first_child, in favor of their
  _query forms over DropQuery::new(payload); each is now exactly that
  wrapper. hit_test_closest, in favor of resolve, which also ranks
  through the provider's collision policy (equal-distance fallback ties go
  to the later record there, the earlier record in the deprecated helper).

Fixed

• One registry acceptance pipeline. The payload-only lookups above now
  run the same acceptance as the built-in components: accepts,
  accepts_query, and allowed_effects negotiation. A custom source
  using them no longer targets zones a Draggable would skip.
• Pointer samples at the exact viewport corner track.
  DndContext::update_pointer used to drop every (0, 0) sample as a
  synthetic-event artifact, so a drag reaching the corner kept its
  previous position. It now drops only a (0, 0) that jumps in from more
  than 256 CSS px away; a sample continuing from nearby is real and is
  applied.
• Ctrl/Cmd+click moves the range anchor. Selection::toggle re-anchors
  on the toggled key, so a following Shift+click ranges from it, as the
  documented click convention promised.
• FileDropZone hover pairing. A zone that becomes disabled while a
  drag hovers it now reports on_hover(false); a zone disabled throughout
  no longer reports a false it never paired with a true.
• AutoScroll sampling is bounded. Scroll-offset reads coalesce to one
  in flight, so a hovering pointer no longer issues one renderer round-trip
  per pointermove; the final offset after a burst is still observed.
• Custom collision ranking is O(n log n). Registration order is
  indexed once instead of scanned per comparison.
• SortableList and SortableGrid retire their pointer-capture flag on
  every return to Idle, matching Draggable.
• CI runs on pushes to dev (the workflow filtered on a branch that no
  longer exists), and the contributor docs pin the same rumdl version CI
  runs.

Changed

• DndContext's PartialEq documents that it compares handle identity
  (the shared announcement signal), never drag state.
