fix(runner): batch auto-install to prevent race conditions and silent UI

- Auto-install now batches all registrations into a single deferred
  install call (200ms debounce), preventing race conditions where
  multiple deferred installs would reject each other
- Silent auto-install no longer pops open the Glaze UI window
- runner.install() accepts { silent: true } option to suppress UI
  and notifications
- Add CI workflow (stylua format check + luacheck lint)
- Add .stylua.toml and .luacheckrc configs
- Fix empty if branch lint warning in runner.lua
- Apply stylua formatting to checker.lua and health.lua
