fix(plugin): screenshot limit, version/build fields, delete button, workspace scripts

- list_screenshots: bump limit 12 → 50 so users can scroll further back
- Add versionString + buildId to DeckyVaultImportV1, SessionData, and
  buildImportPayload. Import endpoint now saves them on new game versions.
- Screenshot delete button in preset detail modal: owner/admin sees a
  trash icon on hover that calls DELETE /api/performance/:id/screenshots/:sid
- Root workspace scripts for plugin workflow:
  bun run plugin:build  | plugin:zip | plugin:release | plugin:deploy
- Add deploy.sh (SSH scripts to push plugin to Deck)
