96199c4fee feat(cli): add langgraph deploy logs subcommand (#7100)
Add a `langgraph deploy logs` subcommand to fetch build and
deploy/server logs from LangSmith deployments.

## Changes

- **`host_backend.py`**: Add `get_build_logs()` and `get_deploy_logs()`
methods, plus `langsmith_url` support.
- **`helpers.py`** (new): Log formatting (`format_log_entry`,
`format_timestamp`, `level_fg`) and resolution helpers
(`resolve_deployment_id`).

## Usage

```bash
# Deploy logs (latest 10)
langgraph deploy logs --deployment-id <id> --limit 10

# Error logs by name
langgraph deploy logs --name gtm-agent --level ERROR

# Build logs
langgraph deploy logs --deployment-id <id> --type build

# Tail logs (Ctrl+C to stop)
langgraph deploy logs --name gtm-agent --follow
```

## Tests

56 unit tests passing covering host backend methods, log formatting, and
helper functions.
