### CrawlerClientFactory

Pattern-based client selection (from `crawler/client.xml`):
- `http:.*`, `https:.*` → SwitchableHttpClient
- `file:.*` → FileSystemClient
- `smb:.*` → SmbClient (SMB2+), `smb1:.*` → SmbClient (SMB1)
- `ftp:.*`, `ftps:.*` → FtpClient
- `storage:.*` → StorageClient, `s3:.*` → S3Client, `gcs:.*` → GcsClient
