feat(wrangler): add wrangler auth token command

[ascorbic]

Fixes #10095.

Adds a new wrangler auth token command that retrieves the current authentication credentials for use with other tools and scripts. This is similar to gh auth token in the GitHub CLI.

The command supports all Wrangler authentication methods:

• OAuth token from wrangler login (automatically refreshed if expired)
• API token from CLOUDFLARE_API_TOKEN environment variable
• API key/email from CLOUDFLARE_API_KEY + CLOUDFLARE_EMAIL (requires --json flag)

Basic usage:

wrangler auth token

JSON output with token type:

wrangler auth token --json
# Returns: { "type": "oauth", "token": "..." }
# Or: { "type": "api_token", "token": "..." }
# Or: { "type": "api_key", "key": "...", "email": "..." }

Implementation notes:

• Outputs raw token value (no banner) for easy scripting via printBanner: false
• Errors with helpful message if using API key/email without --json (no single token to return)
• Refactored internal LocalState to localState for consistency
• Added getOAuthTokenFromLocalState() function that only handles OAuth tokens from local state
• Added JSDoc documentation for auth priority behavior in getAuthFromEnv()

Human Review Checklist:

• Verify the --json output format is appropriate for all three auth types
• Verify the error message for API key/email without --json is helpful
• Verify the auth namespace is the appropriate location for this command
