Mass-converts all array() literals to [] across lib/, tpl/, tst/ as
discussed in #1640. PHP supports short array syntax since 5.4 and the
project's required PHP version is 7.4+, so this is a pure stylistic
change with no behavior impact.
Also flips the StyleCI configuration so future PRs are checked against
short_array_syntax instead of long_array_syntax. Per @elrido in #1640,
the StyleCI swap and the mass change need to land together so no
branch breaks under the wrong rule.
Generated with `php-cs-fixer fix --rules=array_syntax` against the
.styleci.yml finder paths. 39 files touched, 487 insertions / 487
deletions (every change is a single-token replacement). Verified:
- `php -l` clean on all touched files
- `phpunit` from `tst/`: 230 / 230 tests pass (with 6329 assertions),
excluding `ControllerWithGcsTest` which fails on PHP 8.5 because of
an unrelated upstream `google/cloud-core` deprecation. The same 14
GCS-suite errors reproduce on `master` before this change.
Closes#1640
