Headless drive e2e + iOS/Android e2e CI jobs + faster test setup

[tiensonqin]

Summary

Test-time work in four parts, plus the fixes needed to un-break CI (main was failing before this PR):

1. Headless e2e via drive, running in the existing CI gate. A new drive alcotest suite mounts the real chat app in-process — Drive.Session + Lui_app.create with a drain host stub that answers pending_effects with canned projections (mirroring the native bridge's Dequeue/ApplyCoreSnapshot/ResolveEffect sequences) — then replays .drive scenario scripts checked into shared/test/logseq_chat/drive/. Nine scenarios cover cold-start → create-graph, composer capture, settings (language radio, appearance theme, tabs sheet), encrypted-graph unlock, native search, graph switch + context-menu delete, journal rendering → tap-to-edit → editor toolbar, and outliner text-change → return commit. The suite sits inside @shared/native/runtest, so ocaml-core CI runs it — no simulator, ~3s total. The host stub seeds two journal rows and answers TapOutlinerBlockEffect/ChangeOutlinerTextEffect/ReturnOutlinerEditorEffect with projection_outliner_editing snapshots and updated rows. New drive pin — logseq/drive#1 (scenario change command + empty-string token fix).

• Selector gotcha worth knowing: text:"Confirm" substring-matches any string prop — button.graph-add.confirm's a11y id matches too — so iOS dialog buttons (which have no a11y id) need kind:button&prop:text=Confirm (exact prop equality). Similarly text:"Theme" hits the label text node, not the select — use kind:select.

2. iOS/Android e2e in CI (new .github/workflows/e2e.yml):

• ios-e2e on macos-15: Maestro + opam/duniverse setup (same cache steps as ocaml-core), Xcode 26 selected for lui's swift-tools 6.2, build-mobile-ios-simulator.sh, boot a freshly-created simulator, run the smoke module.
• android-e2e on ubuntu-latest + KVM: Flutter/Gradle/Maestro setup, reactivecircus/android-emulator-runner boots an x86_64 emulator, runs the smoke module (signed-out + local-graph-setup + capture). LOGSEQ_CHAT_ANDROID_ABI=x86_64 cross-builds liblogseq_chat_core.so for the emulator arch via Gradle → build-android-native.sh.
• db-sync server runs in CI (./.github/actions/db-sync-server): checks out logseq/logseq@feature/native-mobile-app, installs JDK21 + Clojure CLI + pnpm, clojure -M:cljs release db-sync-node, starts DB_SYNC_PORT=8787 in the background (~70s warm; ~/.m2/~/.gitlibs/pnpm store/node_modules cached). Both jobs point the app at http://127.0.0.1:8787 — iOS reaches it via simulator host loopback, Android via the script's adb reverse tcp:8787 (now gated on LOGSEQ_CHAT_E2E_BASE_URL). Smoke flows sign in through the in-app Cognito form ("Use without an account" → e2etest/[REDACTED SECRET], overridable via LOGSEQ_CHAT_E2E_USERNAME/_PASSWORD) → real JWT → real sync graph creation end-to-end.
• Triggers: every PR + push to main (smoke only), nightly cron runs the full all suites, workflow_dispatch takes module inputs. OCaml cross toolchains (_build/apple-toolchains, _build/android-toolchain, _build/android-*) are cached — warm runs skip the ~10min OCaml-from-source bootstrap. These jobs are inherently minutes-scale (toolchain + build + simulator boot); the ocaml-core gate remains the fast (~1min warm) check.
• Script fixes needed for CI: build-mobile-ocaml.sh/both e2e scripts resolved dune via opam exec --switch=5.5.0, but CI's setup-ocaml local switch is _opam (unnamed) — now prefer $DUNE/command -v dune. test-android-e2e.sh cd'd to repo_root/Flutter, which only worked on case-insensitive macOS — fixed to flutter/ (runner test updated). Data-wipe per flow now recreates <container>/tmp — the OCaml core writes its initial snapshot there and crashed on every flow after the first.

3. Faster per-flow iOS e2e setup (scripts/test-ios-e2e{,-suite}.sh):

• Wipe the app's data container + defaults delete instead of simctl uninstall+install per flow — the binary never changes, so reinstalling was pure overhead. LOGSEQ_CHAT_IOS_E2E_REINSTALL=1 restores the old path.
• One LOGSEQ_CHAT_E2E_RUN_ID + shared LOGSEQ_CHAT_E2E_SEED_CACHE: the first flow per fixture mode runs the Maestro graph-setup + checkpoint wait + logseq_chat_e2e_seed.exe, caches the seeded Documents/graphs; later flows copy it into a fresh container. ~13 outliner-fixture flows → 1 UI setup.

4. CI fixes for the #main-pin regression from #11 (main's ocaml-core was red):

• ci.yml: the private-pin duniverse clone step only matched #[0-9a-f]{40}; #main pins were never vendored → persistent_sorted_set_ocaml resolved from _opam and the workspace → dune library-name conflict. Now matches any #ref with a FETCH_HEAD fallback.
• ci.yml: setup-ocaml is bypassed when the ~/.opam root + _opam switch caches both hit (it ran an unconditional ~40s opam update); duniverse cache key now includes the workflow files.
• storage_codec: datascript-ocaml@main added optional storage_{eavt,aevt,avet}_metadata fields to storage_root; decode/encode them so roots round-trip.

Test plan

• dune build @shared/native/runtest — 716 tests pass locally, including all 9 drive scenarios
• iOS smoke (build + 4/4 flows incl. Cognito sign-in → sync-graph creation against a locally-built db-sync server) verified end-to-end on a macOS session
• Android toolchain proven through APK build + app launch on CI; the db-sync-in-CI path is new — first real run may need iteration; LOGSEQ_CHAT_IOS_E2E_REINSTALL=1 restores the old reset path
