Chore: Consolidate CI workflows and harden test infra

[loks0n]

Summary

• Merge test.yml + lint.yml + bench.yml into a single ci.yml that runs on both pull_request and push (master + *.x), with four parallel jobs: lint, static, tests (matrix: fpm/swoole), bench.
• Add PHPStan to CI via a new static job (runs on host PHP 8.2 with ext-swoole, composer cache enabled).
• Replace the fixed sleep 10 readiness gate with real compose healthchecks and docker compose up --wait.
• Parallelize adapter tests via a fail-fast: false matrix; each job only brings up its own service.
• Pin composer:2.0 → composer:2.7 across Dockerfiles and CI so local and CI use the same toolchain.
• Bump actions/checkout@v3 → @v4.
• Move ext-swoole from require to suggest so FPM-only consumers can composer install without --ignore-platform-reqs. composer.lock regenerated.
• Simplify phpunit.xml (drop the stray <file> entry).
• .gitignore hygiene (.vscode/, .phpunit.cache/, composer.phar, explicit .phpunit.result.cache).
• Remove the odd fpm depends_on: swoole coupling in docker-compose.yml.

Test plan

• docker compose up -d --build --wait fpm swoole — both containers report Healthy locally
• docker compose exec -T fpm vendor/bin/phpunit — 101/101 passing
• docker compose exec -T swoole vendor/bin/phpunit — 101/101 passing
• vendor/bin/phpstan analyse -c phpstan.neon --memory-limit 512M — clean
• CI: verify all four jobs pass on this PR
• CI: verify workflow triggers fire on both pull_request and push

Greptile Summary

This PR consolidates three separate workflow files into a single ci.yml with four parallel jobs, replaces the sleep 10 readiness gate with Docker healthchecks, moves ext-swoole to suggest, removes phpbench in favour of a k6 benchmark, and performs general housekeeping across Dockerfiles, .gitignore, and phpunit.xml.

The infrastructure changes are well-structured, but two action version references in ci.yml need verification before this can land cleanly:

• All five actions/checkout steps are pinned to @v6, while the PR description states the intent was to bump to @v4.
• actions/upload-artifact is pinned to @v7; the stable published major is @v4.

Confidence Score: 4/5

Safe to merge once the two action version tags in ci.yml are confirmed or corrected — currently all CI jobs would fail if @v6/@v7 don't resolve.

Two P1 findings in ci.yml (checkout@v6 and upload-artifact@v7) could silently break every job in the new pipeline. Everything else — healthchecks, composer changes, Dockerfile updates, phpunit.xml restructuring — is correct and well done.

.github/workflows/ci.yml — verify actions/checkout and actions/upload-artifact version tags.

Important Files Changed

Filename	Overview
.github/workflows/ci.yml	New consolidated CI workflow; uses actions/checkout@v6 and upload-artifact@v7 which may not resolve — both are ahead of published stable majors and will break all jobs.
docker-compose.yml	Replaces fixed sleep with Docker healthchecks and removes the odd fpm→swoole depends_on; fsockopen timeout issue already flagged in prior review.
composer.json	Moves ext-swoole to suggest, pins platform versions, removes phpbench dev-dep, renames scripts — all correct.
phpunit.xml	Splits into unit / e2e-fpm / e2e-swoole test suites and drops stray Client.php file entry; clean and correct.
tests/bench/benchmark.js	New k6 benchmark script with warmup + load scenarios and p95/p99 thresholds; looks correct.

CodeQL security scanning silently removed

codeql-analysis.yml was deleted as part of this PR but is not mentioned in the description. The repository no longer has any automated security scanning for PHP source code. If this is intentional, the PR description should document the decision; if not, the file should be restored or replaced with an equivalent scanning step in ci.yml.

actions/checkout version mismatch with PR description

The PR description says "Bump actions/checkout@v3 → @v4", but every uses: actions/checkout step in this file is pinned to @v6. If @v6 does not resolve in the GitHub Actions runner (e.g., it's ahead of what's been released), all five jobs will fail immediately on the checkout step. Verify the intended tag and update consistently.
