CI: Default SESSIONS_WEB_DEPLOY_SMOKE_GATE=1 in ci-local after #1967 green

[PurHur]

Problem

#1893 ✅ added 005-SessionsWeb deploy + PHPC_DEPLOY_ROOT CGI flash to script/deploy-smoke.sh. #1967 wires opt-in SESSIONS_WEB_DEPLOY_SMOKE_GATE=1 into ci-local.sh (default still 0 in script/ci-defaults.env).

VM session smoke is already default-on (SESSIONS_WEB_SMOKE_GATE=1, #1894 ✅). Deploy regressions for session file paths / Set-Cookie under dist layout only surface when contributors remember the opt-in flag.

Goal

Flip SESSIONS_WEB_DEPLOY_SMOKE_GATE default from 0 → 1 in script/ci-defaults.env once #1967 opt-in path is green on harness + Docker for several batches.

Implementation hints

Piece	Path	Notes
Default	script/ci-defaults.env	SESSIONS_WEB_DEPLOY_SMOKE_GATE="${...:-1}"
CI hook	script/ci-common.sh	ci_run_deploy_smoke already gated
Makefile	Makefile deploy-smoke target	Runs 005 when gate=1
Docs	docs/local-ci-matrix.md	Row default 1
Tests	test/unit/CiScriptsTest.php	Assert new default string
Doctor	lib/Doctor.php	✅ row when gate=1 (#1969)

Precedent: #1923 flips SESSIONS_WEB_AOT_SMOKE_GATE after #1921.

Acceptance criteria

• ./script/ci-local.sh runs 005 deploy smoke without extra env on LLVM harness
• SESSIONS_WEB_DEPLOY_SMOKE_GATE=0 ./script/ci-local.sh skips 005 deploy only
• test/unit/DeploySmokeScriptTest.php green

Verification (local / Docker only)

make docker-build-22
./script/docker-ci-local.sh   # full gate with new default
SESSIONS_WEB_DEPLOY_SMOKE_GATE=0 ./script/ci-local.sh   # skip 005 deploy slice

No GitHub Actions (#394 ✅).

Dependencies

• CI: SESSIONS_WEB_DEPLOY_SMOKE_GATE opt-in in ci-local after #1893 #1967 — opt-in ci-local wiring (land first)
• Testing: 005-SessionsWeb phpc deploy + PHPC_DEPLOY_ROOT CGI smoke #1893 ✅ — deploy smoke implementation
• Testing: 005-SessionsWeb AOT link + two-request CGI execute smoke #1891 ✅ — AOT session execute (deploy uses AOT binary)
