Testing: MiniWebAppJitProjectTest PATH_INFO hello + contact POST (#1759)

[PurHur]

Summary

Closes #1759.

Extends MiniWebAppJitProjectTest (phase 2 of #587) with two JIT project smokes that mirror existing VM/AOT coverage:

• PATH_INFO hello — MiniWebAppCgiEnv::pathInfoHello('Dev'), asserts Hello Dev
• Contact POST — MiniWebAppCgiEnv::postQueryRouteContact(), asserts Thank you, PostDev

Reuses shared CGI helpers (no duplicated env strings). On JIT compile failure, runIndex() skips with an explicit not jittable message (#475, #58) instead of a bare non-zero exit.

Test plan

MINIWEBAPP_JIT_PROJECT_GATE=1 ./script/docker-ci-local.sh --filter MiniWebAppJitProjectTest
# or targeted (tar bind-mount harness):
MINIWEBAPP_JIT_PROJECT_GATE=1 ./script/docker-ci-local.sh  # ci-local @group miniwebapp-jit-project

On this Runforge harness, jit-runtime-probe.php segfaults (bin/jit.php -l exit 139), so all three tests skip in setUp with the existing MCJIT probe message — acceptable per #1759 acceptance (pass or explicit skip). On hosts with a working LLVM MCJIT probe, all three routes should assert.
