feat: add support for Laravel 13 and PHP 8.5

[alright]

What / Why

Adds support for Laravel 13 and PHP 8.5 without dropping any currently supported version.

How

composer.json

• illuminate/contracts: ^9.0||^10.0||^11.0||^12.0 → …||^13.0
• orchestra/testbench (dev): ^10.0.0||^9.0.0 → ^11.0.0||… (Testbench 11 is the line targeting Laravel 13)
• php stays ^8.0 — it already admits 8.5, so no change was needed there.

CI

• run-tests.yml: matrix is now php: [8.5, 8.4] × laravel: [13.*, 12.*, 11.*], with testbench: 11.* mapped to Laravel 13. Laravel 11 is excluded on PHP 8.5 since it predates that release and isn't tested against it upstream — 20 jobs, up from 8.
• phpstan.yml and tag.yaml now run on PHP 8.5.

rector.php (separate commit, chore(rector): … — see notes below)

No source changes were required: the suite runs clean on 8.5 with zero PHP deprecations.

Screenshots / Output (if applicable)

Ran locally against real installs on each new matrix combination (plus L11 as a regression check):

PHP	Laravel	Stability	Result
8.5	13.26.1	prefer-stable	47 passed (179 assertions)
8.5	13.12.0	prefer-lowest	47 passed
8.5	12.67.0	prefer-stable	47 passed
8.4	13.26.1	prefer-stable	47 passed
8.4	11.x-dev	prefer-stable	47 passed

• pest --display-deprecations --display-warnings --display-notices on PHP 8.5 / Laravel 13: no deprecations reported.
• Type coverage still 100%.
• spatie/laravel-package-tools: ^1.16 resolves to 1.93.x under Laravel 13, so no bump is needed there.

Type of change

• Bug fix
• New feature
• Refactor / internal cleanup
• Docs only
• Tests only
• Chore (CI, build, tooling)

Checklist

• Tests added/updated and pass locally (composer test) — no new tests; the existing 47 cover the change, and they were run against every new matrix combination
• Code formatted (./vendor/bin/pint) — rector.php is the only PHP file touched and it passes pint --test
• No writes to vendor/composer/autoload_classmap.php (tests use hookpress.composer.classmap_path)
• README / docs updated (if user-facing) — Requirements section notes the CI-tested versions
• Backwards compatible (or breaking changes clearly documented) — constraints are only widened

Notes for reviewers

The second commit is tooling, split out so you can drop it if you'd rather handle it separately. composer run rector is currently broken on a fresh install, and one of its rules is actively dangerous:

1. strictBooleans: has been removed from Rector's withPreparedSets() upstream, so rector.php throws Unknown named parameter $strictBooleans and the pre-commit hook aborts. The set no longer ships with Rector, so the flag is just dropped.
2. ForeachToArrayAnyRector (PHP 8.4 set) rewrites the body of src/polyfills.php::array_any() into a call to array_any() — i.e. infinite recursion. It's now skipped for that one file.
3. The Rector PHP set is bumped 8.4 → 8.5 to match.

Two things I deliberately left alone:

• PHPStan reports 3 errors, but they already fail on main. I checked out main in a separate worktree, installed on PHP 8.4 / Laravel 12, and got the identical three. Since composer.lock is gitignored, CI always resolves the newest larastan/PHPStan, so this is pre-existing drift rather than fallout from this PR:

  • src/Commands/ShowCommand.php:21 — is_string() on a non-falsy-string always evaluates to true
  • src/Conditions/HasMethod.php:57, src/Conditions/HasProperty.php:52 — (string) $type on ReflectionType, whose __toString() is doc-deprecated since PHP 8.0 (it emits no runtime notice on 8.4 or 8.5 — I verified).

  fix: stop relying on the deprecated ReflectionType::__toString() #21 fixes all of these, off main and independent of this PR, so neither diff carries the other's changes. PHPStan goes green here once it lands.

• Repo-wide pint churn. A current Pint reformats 18 unrelated files (fully_qualified_strict_types now applies more broadly). Per CONTRIBUTING's "no unrelated changes bundled in the PR", I left that out — it's independent of this change and belongs in its own chore(style) commit.
