xcb3dandAnthony Eid 759349131a debugger: Fix crash when dragging pane items to split view (#46806)
## Summary

Fixes crash when dragging debugger panel items
(terminal/console/variables/frames) to another pane as split view.

  **Root causes:**
1. Double borrow panic - `pane_group.split()` was called synchronously
inside a `Context<Pane>` update, causing "cannot update Pane while it is
already being updated"
2. `unwrap()` calls that panic when items are in transition during drag
operations
3. `debug_assert!` in `pane_at_pixel_position` fails when `members` and
`bounding_boxes` are temporarily out of sync after deferred split

  **Fixes:**
- Defer entire split+move operation via `cx.spawn_in()` to avoid double
borrow
- Replace `unwrap()` with graceful early returns in `activate_item` and
`run_in_terminal`
- Handle `members.len() != bounding_boxes.len()` gracefully in
`pane_at_pixel_position`

Closes #46784

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
