fix(auth): update terminology to 'sign in' and 'sign out'

[clocky]

Summary

This PR updates the terminology from "login" and "logout" to "sign in" and "sign out" across the Gemini CLI, its documentation, and its user interface. This change ensures consistency with modern Google authentication standards and improves clarity for users.

Details

• Renamed slash commands: /login is now /signin and /logout is now /signout.
• Backward Compatibility: Added altNames support so that /login and /logout continue to work while pointing to the new commands.
• UI String Updates: Updated all UI labels from "Login with Google" to "Sign in with Google" and from "Logged in" to "Signed in".
• Improved UI Messaging: Refined several UI messages for clarity (e.g., "Waiting for auth..." is now "Waiting for authentication...", and "CTRL+C" is now "Ctrl+C").
• Documentation: Updated the README.md and extensive documentation in the docs/ directory to reflect the new terminology.
• Testing: Updated unit and integration tests to align with the new command names and strings, including verification of altNames.

How to Validate

1. Run the Gemini CLI and verify that the new /signin and /signout commands are available.
2. Verify altNames: Confirm that /login and /logout still function as aliases for the new commands.
3. Initiate the authentication flow to confirm the updated "Sign in with Google" label.
4. Review the README.md and documentation for consistency.

Pre-Merge Checklist

• Updated relevant documentation and README (if needed)
• Added/updated tests (if needed)

Code Review

This pull request consistently updates the terminology from 'login'/'logout' to 'sign in'/'sign out' across the codebase, including UI components, commands, tests, and documentation. The changes are thorough and align with the goal of standardizing authentication language. I've found one issue in a test file where a mocked error message was not updated to match the new test expectation, which will cause the test to fail.
