feat(android): add accessibility xpath audit CLI and report

[quanruzhuoxiu]

Summary

• add a TypeScript CLI for source, fresh, and revisit Android Accessibility captures
• preserve screenshots, the raw XML actually used for XPath generation, the complete normalized UiNode tree, per-node diagnostics, visual inventory, and replay results
• generate per-page annotated HTML plus run-level summary and index reports
• keep unexposed visual controls in the audit denominator through a human-reviewed visual inventory

Stack

Part 2 of 3.

• depends on: feat(android): add accessibility xpath audit core #2876
• base branch: feat/android-xpath-audit-core
• next: feat/android-xpath-audit-playground

The CLI defaults to Accessibility capture and does not require CDP. Raw device artifacts remain under the ignored midscene_run/ directory.

Validation

• pnpm exec nx build @midscene/android --skip-nx-cache
• pnpm exec nx test @midscene/android --skip-nx-cache -- tests/unit-test/accessibility-xpath-audit.test.ts tests/unit-test/cache-compatibility.test.ts
• pnpm exec tsx packages/android/scripts/accessibility-xpath-audit.ts --help
• pnpm run lint

The focused suite passed 18 tests.

Superseded by #2892. The replacement stack is self-contained from main and preserves the same review layer.
