chore: reorganize test scripts, add destructive action tests, fix rclone bug

- Move scripts/test-tools.sh and scripts/test-actions.sh → tests/mcporter/
  - Fix PROJECT_DIR path in test-tools.sh (SCRIPT_DIR/.. → SCRIPT_DIR/../..)
- Add tests/mcporter/test-destructive.sh: 2 live + 13 skipped destructive tests
  - stdio transport (no running server required)
  - notifications:delete (create→list→delete), keys:delete (create→delete→verify)
  - 3 new skips: createDockerFolder/updateSshSettings/createRCloneRemote not in API
  - Requires --confirm flag; dry-run by default
- Add tests/mcporter/README.md documenting both scripts and coverage
- Rewrite docs/DESTRUCTIVE_ACTIONS.md: merge test guide, all 15 actions with commands
- Delete docs/test-actions.md (merged into tests/mcporter/README.md)
- Fix rclone.py create_remote: send "parameters" not "config" (API field name)
- Update README.md and CLAUDE.md: 11 tools/~104 actions, new script paths
- Add AGENTS.md and GEMINI.md symlinks to CLAUDE.md
- Bump version 0.4.3 → 0.4.4
