feat(bridge-rector)!: split mock conversions into PHPUnit→Double, PHPUnit→Mockery and Mockery→Double sets

[roxblnfk]

🔍 What was changed

• Mock conversions moved out of phpunit-to-testo into three sets, each with its own folder, config and TestoRectorSetList constant: PHPUNIT_TO_DOUBLE, PHPUNIT_TO_MOCKERY, MOCKERY_TO_DOUBLE.
• New CreateMockToMockeryRector (PHPUnit to Mockery), MockeryToDoubleRector (Mockery to Double, following Double's migration table) and MockeryIntegrationToDoubleRector (MockeryPHPUnitIntegration/MockeryTestCase to VerifiesDoubles).
• Both PHPUnit rules now cover configured and partial mocks, willReturnMap, and every constraint without a dedicated matcher, as a predicate that reproduces PHPUnit's own evaluate().
• Fixed: isType('integer'), Mockery::type('integer') and similar produced a Double matcher that never matched, because Double's Argument::type() reads any name outside its builtin list as a class.
• The skill's Rector scaffolder takes several --set values, and precheck.php finds the sets in the flattened config/.

Breaking changes

• phpunit-to-testo no longer converts mocks. Add PHPUNIT_TO_DOUBLE or PHPUNIT_TO_MOCKERY next to it.
• CreateMockToDoubleRector moved to Testo\Bridge\Rector\PhpunitToDouble.

Review notes

• Two deliberate departures from Double's migration table: Mockery::mock(X) becomes Double::for(X)->strict(), since a plain Mockery mock throws on unconfigured calls, and shouldNotHaveBeenCalled() becomes received('__invoke')->never(), since Mockery's version only concerns __invoke, not unused().
• Mockery compares plain values with ==, Double with === for scalars. Tests relying on coercion fail after conversion by design.

Checklist

• How was this tested:
  • Unit tests added
  • Constraint predicates diffed against real PHPUnit evaluate() over 56 constraints x 39 values
  • Generated code run against real Double and Mockery
  • composer test:ci -- --type=!bench run locally (only failure is the known local Xdebug nesting in BenchAttr::rangeSum)

Documentation

• Bridge README, FEATURE_PARITY.md, per-folder TODO.md, skills testo-migrate-from-phpunit and testo-test-doubles.
