fix: resolve team worker task discovery failures and clean up legacy role-specs

- Remove owner name exact-match filter from team-worker.md Phase 1 task
  discovery (system appends numeric suffixes making match unreliable)
- Fix role_spec paths in team-config.json for perf-opt, arch-opt, ux-improve
  (role-specs/<role>.md → roles/<role>/role.md)
- Fix stale role-specs path in perf-opt monitor.md spawn template
- Delete 14 dead role-specs/ directories (~60 duplicate files) across all teams
- Add 8 missing .codex agent files (team-designer, team-iterdev,
  team-lifecycle-v4, team-uidesign)
