fix(quality): resolve cs-fixer formatting + Psalm PossiblyFalseOperand

cs-fixer: removed extra alignment spaces in array key-value pairs across
6 files (KcodeComposerGenerator, Devkit, InitCommand, ProcessExecutor,
KcodeComposerGeneratorTest, ComposerResolverTest). No logic changes.

KcodeComposerGenerator.php:76:
  json_encode() returns false|string; applied (string) cast to satisfy
  Psalm PossiblyFalseOperand. The manifest is a static structure with no
  un-serializable values so the false branch is unreachable in practice.

Result:
  ✓ cs-fixer   passed
  ✓ phpstan    passed
  ✓ psalm      passed (0 errors)
  ✓ phpunit    passed
  ✓ All 4 tool(s) passed
