test: add live macOS File Provider e2e

[aseembits93]

Summary

• add a signed-app live test that exercises the real macOS CloudStorage/File Provider path against scratch Notion content
• verify lazy enumeration and hydration, atomic page replacement, push, create, rename, delete, remote reconciliation, and cleanup
• add a manual self-hosted workflow for a stable pre-approved test identity, plus CI syntax/safety guards and coverage docs

Safety

The live harness requires both explicit live and dedicated-host opt-ins, an exact test bundle id, an enabled loc domain, an unused daemon port, and isolated temporary Locality state. It never resets or unregisters the shared File Provider domain and only archives scratch Notion pages it created.

Validation

• swift test --package-path platform/macos/LocalityFileProvider (21 passed)
• bash tests/ci_workflow_contract.sh
• bash scripts/install-macos-prompt-test-app.test.sh
• bash -n tests/live_macos_file_provider.sh
• disabled-path and dedicated-host refusal checks
• YAML parse and git diff --check

The real kernel round trip is intentionally not run from an ordinary development checkout; the new workflow runs it on a self-hosted Mac whose stable test extension identity has been approved once.
