feat(skills): interactive-simulator-ux-audit + host-driven-xcuitest-e2e + cloudkit-schema-source-of-truth

[wei18]

Summary

Three new first-party skills, genericized from a real shipping project's battle-tested lessons — no project nouns, no issue numbers.

• interactive-simulator-ux-audit — drive a booted iOS Simulator with idb (tap / describe-all / screenshot) to catch navigation, modal, back-stack, safe-area/Dynamic-Island, and offline/signed-out bugs that a fixed-size snapshot render structurally can't show. Covers the no-Homebrew idb install path (direct GitHub release download + an exec wrapper that preserves rpath), the describe-all → tap → screenshot drive loop, device-point vs. screenshot-pixel coordinate spaces, and the stale-build / worktree-launch-crash false-negative traps.
• host-driven-xcuitest-e2e — wire launch-the-app XCUITest E2E via Tuist: a native .uiTests target needs its own dedicated scheme with testAction: .targets([...]), not membership in a .xctestplan (the latter builds but fails with "no test bundles available to test"), and its name must avoid colliding with an SPM <Target>UITests package test target. Also covers driving SwiftUI on macOS, where element.tap() throws point.x != INFINITY and app.coordinate(...) resolves to (-inf, -inf) — worked around by anchoring on the window element and clicking finite element frames — plus hittable not being a valid NSPredicate key and locale-stable accessibility queries.
• cloudkit-schema-source-of-truth — one committed .ckdb per app as the schema source of truth, xcrun cktool export/validate/deploy scripted against Development only (management token from an env file, passed positionally since cktool rejects piped stdin, purged after use), and Production promotion as an irreversible, user-owned Console-button-only gate cktool cannot reach. Covers Production fields/indexes being add-only and Just-In-Time schema existing only in Development (a silent-missing-field failure mode).

Bookkeeping

• apple-dev-skills first-party skill count bumped 22 → 25 across plugin.json, marketplace.json, README.md Catalog (+ Install one-liner), and README.zh-Hant.md (manually translated and synced — see below).
• scripts/check-consistency.py: PLUGINS["apple-dev-skills"] 22 → 25, plus its docstring's 34 → 37 total-skills note.
• No version field touched anywhere (left for a follow-up release bump).

Deviation from the dispatch

mise run readme-zh shells out to claude -p to translate README.md. Invoked from inside this (already-nested) agent session it hung indefinitely and had to be killed, truncating the output file. Recovered via git checkout -- README.zh-Hant.md and applied the same edits (three new table rows + the two count bumps) by hand in Traditional Chinese, then updated the trailing <!-- src-sha: ... --> comment to git hash-object README.md's current value. check-consistency.py's zh-Hant freshness check (#4) passes against this manual sync.

Test plan

• python3 scripts/check-consistency.py — all 8 checks pass (OK — 2 plugins (25/12), catalog + counts + zh-Hant consistent.)
• Repo-wide grep for sudoku|minesweeper|GameShellKit|GameAppKit|SudokuCoreKit|MinesweeperCoreKit and for #<issue-number> patterns inside the 3 new skill dirs — clean (only pre-existing wei18/Sudoku provenance-section references remain, unrelated to this PR)
• Frontmatter name: matches each skill's directory name; all three descriptions under the 800-char gate
