refactor(commands): replace briandowns/spinner with stloader

Replace all usages of github.com/briandowns/spinner with the new
stloader package. All commands now have consistent visual feedback
with the shining text effect.

Changes:
- grep.go: Use stloader with "Searching commands..." text
- auth.go: Use stloader with "Waiting for authentication..." text
- query.go: Use stloader with "Querying AI..." text
- Remove unused briandowns/spinner dependency
