v1.0.0-next.4

Patch Changes

• a3cb04d: Sync the dev toolbar redesign from Solid Start: panel layout with a call list beside a detail pane, collapsible sections, body-first content viewers, request timing, unhandled rejection capture, drag limited to the toolbar pill, and source map tracing through @jridgewell/trace-mapping. Stack parsing moves from error-stack-parser to error-stack-parser-es/lite, dropping the stackframe transitive dependency.
