Laravel 13.x Compatibility

[sudhansu08]

Adds Laravel 13 support to the 3.x (Filament v3) line by widening the illuminate/contracts constraint, mirroring #202 which added Laravel 13 support to the 4.x branch.

Summary

• illuminate/contracts: ^10.0|^11.0|^12.0 → ^10.0|^11.0|^12.0|^13.0

No code changes are required — SelectTree uses only stable illuminate/support helpers (Arr, Collection) and Eloquent relation types (BelongsTo, BelongsToMany) for relationship traversal, none of which changed in Laravel 13. This matches the result of #202 on the 4.x line, which needed no source changes either.

Can you let me know if you tested it properly?

Hi @CodeWithDennis 👋 — yes, here's exactly what I did.

The change is constraint-only — it only widens illuminate/contracts to include ^13.0; no source files are touched. It mirrors #202 on the 4.x branch, which also needed no code changes. The 3.x SelectTree uses only stable Laravel APIs (Illuminate\Support\Arr/Collection and the BelongsTo/BelongsToMany relation types for tree traversal), none of which changed in Laravel 13.

Verified on a real Laravel 13 install:

Installed this branch with Laravel 13.16.1 + Filament v3.3.54 (+ Testbench 11 / Pest 4) — Composer resolves cleanly and package:discover boots the service provider.
The package's test suite (ExampleTest, ArchTest) passes on Laravel 13.
Added a quick functional check: SelectTree::make()->relationship(...)->searchable()->multiple()->withCount()->independent(false) instantiates, configures, and resolves its view correctly on L13.
