CI: Default FILE_UPLOAD_WEB_AOT_LINK_GATE=1 in ci-local after #2009 green

[PurHur]

Problem

006-FileUploadWeb AOT link is green when FILE_UPLOAD_WEB_AOT_LINK_GATE=1 (ExamplesCompileTest::test006FileUploadWebAotLink). Defaults remain 0 in script/ci-defaults.env — full ci-local.sh does not exercise 006 link unless env is set manually.

005 pattern: #1946 link gate → #1954 default-on after green.

Goal

1. Flip FILE_UPLOAD_WEB_AOT_LINK_GATE default to 1 in script/ci-defaults.env
2. Document in docs/local-ci-matrix.md and examples/006-FileUploadWeb/README.md
3. phpc doctor --gates (DevEx: phpc doctor --gates lists 006-FileUploadWeb ladder (#1999–#2012) #2010) reflects default-on

Depends on

• CI: Default FILE_UPLOAD_WEB_SMOKE_GATE=1 in ci-local after #2008 green #2009 — VM FILE_UPLOAD_WEB_SMOKE_GATE default-on first (LLVM-independent)
• Green: FILE_UPLOAD_WEB_AOT_LINK_GATE=1 ./script/ci-local.sh --filter test006FileUploadWebAotLink in php-compiler:22.04-dev

Acceptance criteria

./script/ci-local.sh --filter test006FileUploadWebAotLink   # no env override after flip
vendor/bin/phpunit --filter CiScriptsTest   # asserts ci-defaults.env contains :-1

Verification (local / Docker only)

make docker-build-22
docker run --rm -v "$(pwd):/compiler" -w /compiler php-compiler:22.04-dev \
  ./script/ci-local.sh --filter test006FileUploadWebAotLink

PM sync — batch 103

Blocked on: #2009 (FILE_UPLOAD_WEB_SMOKE_GATE default-on) per issue Depends.

Green today (opt-in): FILE_UPLOAD_WEB_AOT_LINK_GATE=1 ./script/ci-local.sh --filter test006FileUploadWebAotLink in Docker.

After #2009 merges: this flip is LLVM link-only (no serve/loopback). Pair #2010 doctor output in same or follow-up PR.

PM unblock (batch 105): Dependency #2009 closed via PR #2022 — FILE_UPLOAD_WEB_SMOKE_GATE defaults to 1 on master. AOT link flip is ready for a focused PR:

• Change FILE_UPLOAD_WEB_AOT_LINK_GATE:-0 → :-1 in script/ci-defaults.env
• Update CiScriptsTest, docs/local-ci-matrix.md, examples/006-FileUploadWeb/README.md
• Green check: ./script/ci-local.sh --filter test006FileUploadWebAotLink in php-compiler:22.04-dev

Next in ladder: #2012 (AOT execute default-on after this lands).
