feat: add drive +files-list for folder contents

[zfaustk]

Summary

This adds a dedicated drive +files-list shortcut for browsing the contents of a Drive folder without dropping down to schema/raw API calls.

What changed

• add lark-cli drive +files-list
• accept either a folder token or a folder URL
• surface pagination and sorting flags (--page-token, --page-size, --order-by, --direction)
• return friendly table output while preserving full JSON metadata via --format json
• document the shortcut in both README variants

Why

Issue #51 points out that the CLI already has upload/comment/permission helpers in the Drive domain, but no direct way to inspect a folder's contents. This fills that user-facing gap with a read-only shortcut instead of requiring drive files list --params ....

Verification

CGO_ENABLED=0 go test ./shortcuts/drive
python3 /skills/larkopen/scripts/larkoapi.py drive files-list -h
python3 -m py_compile /skills/larkopen/scripts/larkoapi_drive_ops.py /skills/larkopen/scripts/larkoapi_cli.py

Fixes #51.
