feat(resource): implement AWS SDK integration for CloudResourceHandler

Browse Source 
Implements real AWS SDK integration for CloudResourceHandler using boto3
as an optional dependency. Key changes:

- Add boto3/botocore as optional [aws] dependency in pyproject.toml
- Implement CloudResourceHandler.resolve() for AWS: builds boto3 session,
  verifies credentials via STS get_caller_identity for account-level types,
  and returns a BoundResource with the resource ARN as sandbox_path
- Implement discover_aws_resources() to enumerate VPCs, subnets, instances,
  S3 buckets, IAM roles, RDS instances, ECS clusters, Lambda functions,
  and EKS clusters via the AWS API
- Implement CloudResourceHandler.discover_children() for AWS resource types
  using the new discovery function
- Implement CloudSandboxStrategy.create/commit/rollback for AWS using a
  tag-based isolation strategy (CleverAgents:PlanId tag)
- GCP and Azure providers still raise NotImplementedError (pending)
- boto3 is optional: handler raises ImportError with helpful install message
  when boto3 is not installed
- Credentials are never logged (existing redaction infrastructure preserved)
- Update cloud_resources.feature to reflect new AWS behavior
- Add comprehensive cloud_aws_sdk.feature with 47 BDD scenarios covering
  all new code paths with mocked boto3

Closes #1021

Feature: AWS SDK integration for CloudResourceHandler
As a CleverAgents user
I want the CloudResourceHandler to use real AWS SDK operations
So that I can resolve and discover AWS cloud resources

Credential values are never logged; the existing

## AWS SDK Integration
When ``boto3`` is available, :meth:`CloudResourceHandler.resolve`
returns a real :class:`~cleveragents.tool.context.BoundResource` for
AWS resource types. Resource discovery populates child types (VPCs,
subnets, instances, etc.) from the AWS API.
``boto3`` is an **optional** dependency. If it is not installed, the
handler raises :exc:`ImportError` with a helpful message.
## Sandbox Strategy
Cloud sandbox isolation uses a **tag-based** strategy: a unique
``CleverAgents:PlanId`` tag is applied to all resources created or
modified during a plan. On rollback, tagged resources are deleted or
reverted. On commit, the tag is removed.
