Fix MiniWebApp POST contact empty name after static guard (#10389 follow-up)

[PurHur]

Summary

• Bind superglobal scope slots from VM context before parent-frame inheritance so a second $_REQUEST['name'] read in the caller stays populated after a static guard method (003-MiniWebApp Router::contactNameIsValid() → dispatch()).
• Treat examples-*-smoke: ok as green in release-readiness.sh --full even when opt-in AOT slices skip (e.g. SESSIONS_WEB_AOT_SMOKE_GATE=0).
• Sync docs/bootstrap-inventory.md line refs after Block.php change.

Follow-up to #10389 (merged header/?? fixes only); this lands the MiniWebApp contact POST regression fix that was developed on the same branch.

Test plan

• RequestSecondReadAfterStaticGuardTest (compliance PHPT)
• MiniWebAppVmCliTest::testPostQueryRouteContactThankYou
• ./script/examples-web-smoke.sh (003 contact PATH_INFO POST)
• ./script/release-readiness.sh --full --json → user_release_ready: yes

Follow-up commits on this branch:

• 0aa3f00 — JitVmHelperLink: add missing use PHPCompiler\JIT (fixes first AOT build fatal on master since php-in-php: inline ??/?-> JIT bridges into helpers; delete CoalesceRuntime/NullsafeRuntime (#10311) #10330).
• f8a9536 — UndefinedVariableHelper: skip guard when LLVM insert block is cleared (BasicBlockHelper::tryGetInsertBlock); fixes LLVM 9 basicBlock(null) during ObGzhandler bootstrap.

ThrowsWeb AOT (007) still fails later with UnexpectedValueException: Object not found in jitBranchEntryBlock() during nested ObGzhandler helper compile — separate from the MiniWebApp/$_REQUEST fix.

005-SessionsWeb POST flash (303 vs 200) reproduces on origin/master as well; not introduced by this PR.

Additional commits on this branch:

• 658d210 — Fix header() bool/response_code args after stmt-level ?? + session_write_close (005-SessionsWeb POST flash 303).
• c204438 — ObGzhandler nested JIT helper compile + resolveJitBranchEntryBlock for JUMPIF (007-ThrowsWeb gets past ob_gzhandler bootstrap).

Verified: examples-web-smoke --sessions-only green, HeaderAfterSessionWriteCloseTest, ObGzhandlerJitRuntimeStandaloneTest, MiniWebApp contact POST.

007-ThrowsWeb AOT link still fails later at LLVM module verify (user-class IR issues — separate from the prior jitBranchEntryBlock fatal).
