## Title

    [AWS CLI v2] Output piped to `less` pager: agent shell hangs, or 'Unable to redirect output to pager' in minimal containers

## Body

    Cause (Documented platform behavior): Default pager configuration; resolved from AWS_PAGER, cli_pager, or PAGER.
    
    Fix status: documented_behavior
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/aws/aws-cli/d22f2115447d212da4af5fc35e440ec7f960aad4/awscli/topics/config-vars.rst (official_docs, unknown, documented_behavior): Pager section: less is the default pager on Linux/macOS; override with AWS_PAGER, cli_pager, or PAGER; set AWS_PAGER="" or use --no-cli-pager to disable.
    - https://raw.githubusercontent.com/aws/aws-cli/d22f2115447d212da4af5fc35e440ec7f960aad4/awscli/errorhandler.py (official_docs, unknown, documented_behavior): Pager failures produce 'Unable to redirect output to pager. Received the following error when opening pager: ...' pointing to aws help config-vars.
    
    Search phrasings: aws cli hangs agent less pager; Unable to redirect output to pager aws; AWS_PAGER empty
