Spot Shell (v0.20.4)

Add CentOS Stream 9 and 10 AMI lookup support

Add new CentOS Stream 9 and 10 operating system values, documentation,
and CLI help entries. Since CentOS does not publish SSM AMI parameters,
add an EC2 DescribeImages-based lookup path using the CentOS owner,
architecture/name filters, and newest CreationDate selection, with tests
covering latest AMI selection and related validation fixes.

Spot Shell (v0.20.2)

Update AWS tests for current behavior and optional credentials

Adjust AWS package tests to match current launch template override and
allowed-AZ filtering behavior, removing coverage for deleted helpers.
Add a shared AWS config loader that skips integration-style tests when
credentials or region are unavailable, and update affected image, key,
and VPC tests to use it so `go test github.com/mikeb26/spotsh/aws`
passes without code changes.

Spot Shell (v0.20.0)

Propagate spotsh tags to AMIs and infer launch user

Copy the `spotsh.user` and `spotsh.os` tags from the source instance
onto newly-created AMIs, and update launch handling to treat `--user` as
explicit input while best-effort deriving it from AMI tags when
launching by AMI. Preserve the existing validation failure when no user
can be determined, and ensure image creation uses the selected instance
ID when one is chosen interactively.

Remove internal

functionality defined within internal.
