feat: implement native backup integration Phase 1 (skill wrapping)

[KHAEntertainment]

Summary

Implements Phase 1 of Issue #6: OpenClaw native backup integration.

Changes Made

• CLI Commands: Added ocbs native-backup and ocbs native-verify commands to wrap OpenClaw's native backup CLI
• Bug Fixes:
  • Fixed duplicate imports in skill.py (removed non-existent generate_restore_url)
  • Removed duplicate/broken methods from core.py that were overriding correct implementations

New CLI Commands

# Create native backup (tar.gz archive via OpenClaw)
ocbs native-backup --scope config --verify

# Verify native archive
ocbs native-verify ./2026-03-09-openclaw-backup.tar.gz

Phase 1 vs Phase 2

• Phase 1 (This PR): Skill wrapping - commands that wrap openclaw backup create/verify
• Phase 2: Native backend - OCBS core engine integration with native backup as storage source (already implemented in this branch)

Test Plan

• All 43 tests pass
• CLI help commands work
• Native backup skill methods implemented
• Native backend (Phase 2) fully implemented with tests

Closes #6
