refactor: skills globales — eliminar hardcodes de paths/build tags

- parallel-fix-issues: detecta build tag del proyecto (auto o via BUILD_TAG env/arg),
  usa $(git rev-parse --show-toplevel) para rutas en vez de /home/ubuntu/agents_and_robots
- verify-worktree.sh: acepta BUILD_TAG como env o segundo argumento, auto-detecta con
  //go:build, ejecuta sin -tags si no hay tag configurado
- create-tui: DEVFACTORY_PATH, DEVFACTORY_MODULE y GO_NAMESPACE configurables via env
- init-jupyter: resuelve SKILL_DIR dinamicamente siguiendo el symlink de ~/.claude
- pass-usage: elimina GPG-ID hardcodeado, instruye leer de ~/.password-store/.gpg-id
- settings.json: refresh de formato + effortLevel
