Docs: Add 003-MiniWebApp row to examples benchmark table when VM green

[PurHur]

Problem

examples/README.md benchmark table lists 000, 001, 002, 004 but omits 003-MiniWebApp. #539 ✅ VM lint + serve + PATH_INFO PHPTs are green; the missing row hides compile/run regressions for the north-star app.

#60 closed adding 001-SimpleWeb; no follow-up tracked 003.

Goal

1. Add examples/003-MiniWebApp/ to script/rebuild-examples.php / script/bench.php
2. Regenerate the benchmark table comment block in examples/README.md
3. Document VM column: public/index.php with QUERY_STRING=route=home or PATH_INFO env
4. AOT column: phpc build --project when AOT: Native user-class object model for phpc build --project #568 / Testing: ExamplesCompileTest MiniWebApp AOT lint-only stage (pre #568 link) #624 lint stage unblocks link

Implementation hints

File	Change
script/rebuild-examples.php	Include 003 when MINIWEBAPP_LINT_GATE=1 or BENCH_MINIWEBAPP=1
script/bench.php	VM: bin/vm.php with CGI env; optional JIT/AOT columns
examples/README.md	Regenerate <!-- benchmark table --> block

Scope

• Default on when phpc lint --all examples/003-MiniWebApp exits 0 (same probe as CI: Default MINIWEBAPP_LINT_GATE=1 in web-smoke (post #539) #621)
• Skip AOT timing row until AOT: Native user-class object model for phpc build --project #568 link green (footnote in README)
• Footnote links Reference app: MiniWebApp runtime green (lint 0, VM serve, routes) #539, AOT: Native user-class object model for phpc build --project #568, Testing: ExamplesCompileTest MiniWebApp AOT lint-only stage (pre #568 link) #624

Acceptance criteria

MINIWEBAPP_LINT_GATE=1 ./script/rebuild-examples.php
grep 003-MiniWebApp examples/README.md

docker run --rm -v "$(pwd):/compiler" -w /compiler php-compiler:22.04-dev \
  MINIWEBAPP_LINT_GATE=1 ./script/rebuild-examples.php

Dependencies

• Reference app: MiniWebApp runtime green (lint 0, VM serve, routes) #539 — VM baseline (replaces Reference app: examples/003-MiniWebApp (router, templates, forms) #67 closed skeleton tracker)
• AOT: Project build mode (entry file + dependency graph) #59 / AOT: Native user-class object model for phpc build --project #568 — meaningful AOT project build times
• CI: Default MINIWEBAPP_LINT_GATE=1 in web-smoke (post #539) #621 — lint gate alignment

Links

• ROADMAP 🗺️ ROADMAP: Compile a small PHP web application (living document) #78 Phase 4
• AOT: Re-enable examples/001-SimpleWeb in benchmark table with runtime GET #60 pattern

Implementation hints (backlog batch 34) — unblock now

#539 ✅ VM lint + serve green — skeleton criterion #67 is done. This issue can proceed for the VM/JIT columns; keep AOT column skipped until #568/#485.

Step	Command / file
Env gate	BENCH_MINIWEBAPP=1 or MINIWEBAPP_LINT_GATE=1 in script/rebuild-examples.php
Entry	examples/003-MiniWebApp/public/index.php with QUERY_STRING=route=home
JIT	bin/jit.php on entry after class JIT (#587)
AOT	phpc build --project — skip timing row until #485 passes
Doc	Update footnote: tracker #539 (not open #67)

MINIWEBAPP_LINT_GATE=1 php script/rebuild-examples.php
grep 003-MiniWebApp examples/README.md

Retarget Dependencies section: #539 replaces #67 for VM gate.
