* style: apply php-cs-fixer to test files
Addresses drift flagged by the default PHP-CS-Fixer config — mostly
adds missing `: void` return types on pre-existing test methods.
No behavioural changes.
* fix: resolve phpstan errors surfaced by qa
- Drop the obsolete `Method ::test*() has no return type specified`
ignore rule — every test method now declares a return type, so
the pattern never matches and phpstan reports it as unmatched.
- Remove `?? []` from two reads of `CallToolRequest::$arguments`;
the property is typed `array` (non-nullable), so the coalesce is
a no-op that phpstan flags.
