[13.x] Modernize Database Query Builder with Native Property Types

[genius-asif-hub]

This PR modernizes the Illuminate\Database\Query\Builder class by adding native PHP property type hints to properties that were previously only type-hinted in docblocks.

Why this is important:

• Static Analysis: Significantly improves the accuracy of PHPStan and Larastan analysis for the core.
• Modernization: Aligns the database component with Laravel 13's push for native PHP 8.2+ type safety.
• Zero Bloat: This is a pure technical improvement that removes documentation redundancy and improves runtime safety without adding new logic or methods.

Changes:

• Added native types to $connection, $grammar, $processor, $bindings, $columns, $wheres, $joins, $limit, $offset, and 15+ other core properties.
• Initialized typed properties to null where appropriate to prevent "uninitialized property" access errors.
• Added necessary imports for IndexHint and others.

Verified with vendor/bin/phpunit tests/Database/ - All tests passing.

You have absolutely 0% chance of getting this merged to the 13.x branch. At a minimum it must go to master, and even then the maintainers are unlikely to accept it.

Adding native types over PHPDoc block ones requires targeting master/14.x

Furthermore, I would advise against changing formatting when this is not part of what the PR is trying to solve

You can type this array:

Suggested change

	* @var array|null
	* @var array<\Illuminate\Database\Query\JoinClause>|null

[shaedrich]

You can narrow this further down:

Suggested change

	* @var bool|array
	* @var bool|array<\Illuminate\Contracts\Database\Query\Expression|string>>

[shaedrich]

You can type this, too:

Suggested change

	* @var array
	* @var array{
	* type: 'Expression'|'Basic'|'JsonBoolean'|'Bitwise'|'NullSafeEquals'|'Null'|'NotNull',
	* column: string|\Illuminate\Contracts\Database\Query\Expression,
	* operator: string,
	* value: mixed,
	* boolean: 'and'|'or'
	* }[]

[shaedrich]

You may type this:

Suggested change

	* @var array|null
	* @var array<\Illuminate\Contracts\Database\Query\Expression|string>|null

[shaedrich]

See $where

[shaedrich]

This might be typed as well:

Suggested change

	* @var array|null
	* @var array{
	* column: \Illuminate\Contracts\Database\Query\Expression|string,
	* direction: 'asc'|'desc'
	* }[]|null

[shaedrich]

Also typeable:

Suggested change

	* @var array|null
	* @var array{
	* query: \Closure|\Illuminate\Database\Query\Builder|\Illuminate\Database\Eloquent\Builder<*>,
	* all: bool
	* }[]|null

[shaedrich]

Same here:

Suggested change

	* @var array
	* @var array<\Closure(\Illuminate\Database\Query\Builder): mixed>
