v0.5.1 — phone input before connection

Login now asks for the phone number before connecting to Telegram. Previously, connection or authorization checks could wait while verbose keepalive messages continued, without ever showing the phone prompt.

• Supply the number explicitly with auth login --phone "+15551234567"; the verification code and optional 2FA password remain interactive.
• Pause SDK diagnostics while reading login input, then restore the previous log level.
• Validate and normalize international phone numbers before connecting.

npm install -g @miolamio/tg-cli@0.5.1
telegram-cli --transport wss auth login --client desktop --phone "+15551234567"

Validation: 1,314 tests pass; TypeScript checking, package build, and a real-terminal prompt check on Node 20 pass. Full sign-in on the affected remote machine still needs confirmation.
