chore(release): bump plugin to 1.0.4

User-facing changes since 1.0.3:
- fix(context-scout): empty-state response when no context bundle is
  installed (cherry-pick of upstream issue darrenhinde#310 spirit)
- refactor: agent permissions allow `question` tool (upstream PR darrenhinde#302)
- fix: update.sh skips node_modules in markdown and shell scans
  (upstream PR darrenhinde#309)
