- Extended `CliAuthAttempt` with `anonRefreshToken` and a migration.
- CLI `POST /auth/cli` accepts optional `anon_refresh_token` (must be an
anonymous user's refresh token for the current project).
- `POST /auth/cli/complete` supports `mode` `check` (anonymous vs none),
`claim-anon-session` (issue tokens for the linked anonymous session),
and `complete` (bind the browser session's refresh token to the
attempt). Completing clears `anonRefreshToken` on the row. We do **not**
merge anonymous account data into the signed-in user (that behavior was
removed as a security risk; the anonymous user remains unchanged).
- Template CLI confirmation page, stack-cli optional
`STACK_CLI_ANON_REFRESH_TOKEN`, SDK/spec updates, and e2e coverage.

## Summary by CodeRabbit
* **New Features**
* CLI login supports attaching anonymous sessions and a multi-mode
confirm/claim/check flow; CLI tools now surface login codes and remove
anon token after use.
* Added interactive CLI auth demo page and a CLI simulator script.
* Client libraries: prompt flow accepts an optional anon token and a
promptLink(url, loginCode) callback.
* **Tests**
* Expanded end-to-end coverage for anonymous CLI sessions,
claim/complete/poll flows, upgrades, and error cases.
* **Documentation**
* Updated prompt CLI docs/spec to describe new options and callback
signature.

## Summary by CodeRabbit
## Documentation
* Updated setup instructions across all documentation to clarify that
the publishable client key is only required when your project
configuration enforces it, removing confusion about unconditional
requirements.
