Add `nextdeploy logs` command to stream CloudWatch logs from Lambda

[aynaash]

Summary

Add a nextdeploy logs command that streams CloudWatch logs from the deployed Lambda function in real-time.

Expected Behavior

# Tail logs in real-time
nextdeploy logs --tail

# Show last 100 log lines
nextdeploy logs --lines 100

# Show logs from last 30 minutes
nextdeploy logs --since 30m

Implementation Notes

• Use AWS CloudWatch Logs SDK (FilterLogEvents or GetLogEvents)
• Lambda log group follows pattern: /aws/lambda/<function-name>
• Function name is available from nextdeploy.yml config
• Use polling with FilterLogEvents + nextToken for tail mode

Files to Create/Modify

• cli/cmd/logs.go — [NEW] Cobra command definition
• cli/internal/serverless/aws_logs.go — [NEW] CloudWatch Logs implementation
• cli/cmd/root.go — Register the new command

Reference

• Look at cli/cmd/ship.go for how AWS credentials are initialized
• The AWSProvider struct in cli/internal/serverless/aws.go already has an AWS config
