fix: switch openclaw agent-sdk dep from file: to npm ^0.1.0, fix plugin upgrade

- openclaw now depends on @vectorize-io/hindsight-agent-sdk@^0.1.0 from npm
  (file: refs don't resolve when installed from npm registry)
- CLI removes old plugin extension dir before reinstalling (openclaw doesn't
  support in-place upgrade)
