[bug\_fix] The security token included in the request is expired

Re-run \`aws sts assume-role\` with \`--duration-seconds 43200\` \(12h max\) or configure \`~/.aws/config\` with \`role\_arn\` and \`source\_profile\` to enable automatic credential refresh instead of exporting static keys to environment variables.

Journey Context:
Developer assumes role via \`aws sts assume-role\` and exports the AccessKeyId, SecretAccessKey, and SessionToken to environment variables or pastes them into ~/.aws/credentials. After 1 hour \(default duration\), API calls start failing with 'The security token included in the request is expired'. Developer checks \`aws configure list\` and sees the credentials are still present, not realizing STS temporary credentials have a fixed lifetime. Developer tries \`aws sts get-caller-identity\` which also fails with the same error. Root cause: The \`DurationSeconds\` parameter defaults to 3600 seconds \(1 hour\) when assuming the role, and the credentials expire regardless of activity. The fix works because it either extends the session duration or leverages the SDK's built-in credential provider chain which automatically refreshes temporary credentials before expiration when using assume-role profiles rather than static environment variables.
