Testing: ServeTest MiniWebApp routes via phpc serve (skipped until #67)

[PurHur]

Problem

#461 extends script/examples-web-smoke.sh (shell + curl). #454 adds ExamplesCompileTest @group miniwebapp (lint/build). There is no PHPUnit ServeTest that boots phpc serve against examples/003-MiniWebApp/ with phpc.json "public": "public" (#443 ✅) and asserts route bodies.

Without an in-suite gate, serve regressions for the north-star app only surface via manual curl or the optional shell harness.

Goal

Add test/unit/ServeMiniWebAppTest.php (or extend ServeTest) that:

Step	Behavior
Setup	phpc serve 127.0.0.1:<ephemeral> examples/003-MiniWebApp (project mode)
GET /?route=home	HTML contains app name from config.php
GET /?route=hello&name=Dev	greeting needle
POST /?route=contact	thank-you body (#248 parity)
GET /?route=api/status	JSON ok (#61)

Scope

• Mark @group miniwebapp and skip while phpc lint --all examples/003-MiniWebApp exits non-zero (skeleton phase)
• Respect PHP_COMPILER_SKIP_SERVE_TESTS=1 (same as Testing: Run HTTP serve integration tests in Docker local CI #234)
• Use ephemeral port + proc_open pattern from existing ServeTest.php
• Flip skip → run when Reference app: examples/003-MiniWebApp (router, templates, forms) #67 closes (document in test docblock)

Acceptance criteria

make docker-build-22
docker run --rm -v "$(pwd):/compiler" -w /compiler php-compiler:22.04-dev \
  ./script/ci-local.sh --filter ServeMiniWebApp

• Skeleton phase: test skipped with message linking Reference app: examples/003-MiniWebApp (router, templates, forms) #67
• After Reference app: examples/003-MiniWebApp (router, templates, forms) #67: test runs and passes in ci-local.sh (no GitHub Actions required)

Dependencies

• Reference app: examples/003-MiniWebApp (router, templates, forms) #67 reference app VM green
• Language: Class methods and property access in JIT #58 / Language: Visibility, constructors, and destructors #145 class dispatch
• Language: include/require in JIT and AOT (multi-file applications) #54 template includes
• Language: break and continue for loops and switch #115 break in route scan loop (public/index.php)
• Web: phpc serve uses phpc.json "public" as docroot when serving a project #443 ✅ public docroot
• Web: Extend script/examples-web-smoke.sh for 003-MiniWebApp routes #461 shell harness (complementary, not duplicate)
