Testing: MiniWebAppJitProjectTest — PATH_INFO hello + contact POST (#587 phase 2)

[PurHur]

Problem

#587 landed MiniWebAppJitProjectTest with a single assertion: home via ?route=home query string. AOT execute coverage is full-matrix (#764 ✅, #1529 ✅: hello PATH_INFO, contact POST, api/status). JIT project smoke still has no signal that PATH_INFO routing or POST bodies work under bin/jit.php for the full MiniWebApp graph.

Regressions in JIT lowering for $_SERVER['PATH_INFO'], $_POST, or template includes on non-home routes would only surface when someone manually curls PATH_INFO URLs through JIT.

Goal

Extend test/unit/MiniWebAppJitProjectTest.php (same @group llvm, MINIWEBAPP_JIT_PROJECT_GATE opt-in):

Test	CGI env helper	Assert
testPathInfoHelloShowsName	MiniWebAppCgiEnv::pathInfoHello('Dev')	body contains greeting + Dev
testContactPostThankYou	MiniWebAppCgiEnv::contactPost(...)	body contains thank-you / form ack

Reuse helpers from MiniWebAppAotExecuteTest / MiniWebAppCgiEnv — do not duplicate env strings.

Implementation hints

Piece	File	Notes
Env fixtures	test/MiniWebAppCgiEnv.php	Add JIT-specific helpers if missing (mirror AOT)
Test class	test/unit/MiniWebAppJitProjectTest.php	@group miniwebapp-jit-project
CI	script/ci-common.sh	Runs when MINIWEBAPP_JIT_PROJECT_GATE=1 (unchanged until #730)
Blockers	#475, #58	Skip individual tests with message if JIT throws not jittable

Acceptance criteria

MINIWEBAPP_JIT_PROJECT_GATE=1 ./script/ci-local.sh --filter MiniWebAppJitProjectTest
# or Docker:
docker run --rm -v "$(pwd):/compiler" -w /compiler php-compiler:22.04-dev bash -lc \
  'MINIWEBAPP_JIT_PROJECT_GATE=1 vendor/bin/phpunit --filter MiniWebAppJitProjectTest'

All three routes (home query, hello PATH_INFO, contact POST) pass or skip with explicit blocker issue — not silent empty stdout.

Dependencies

• Testing: JIT smoke for phpc build --project on 003-MiniWebApp #587 — phase 1 home test (shipped)
• Testing: promote MiniWebAppJitProjectTest to ci-fast when #587 green #730 — promote to ci-fast.sh after green
• Language: JIT include/require compile-time lowering (#54 follow-up) #475 — JIT include lowering if template chain fails

PR #1841 adds testPathInfoHelloShowsName and testContactPostThankYou to MiniWebAppJitProjectTest, reusing MiniWebAppCgiEnv helpers. Harness Docker run: all 3 tests skip at MCJIT probe (jit.php -l segfault); structure matches #1759 acceptance (explicit skip, not silent stdout).
