Make CheckAWSAuth, UploadToS3, ImportSnapshot, and RegisterAMI public so
a build server can run them individually (e.g. Marketplace publishing
after RegisterAMI). Rename BuildAMI to BuildAndImportAMI, now a thin
orchestrator over them. Each step records into Result and returns its
artifact; the AWS steps guard on their predecessor and error clearly if
called out of order.

Replace the four aws CLI shell-outs (s3 cp, ec2 import-snapshot,
describe-import-snapshot-tasks, register-image) with aws-sdk-go-v2 S3
and EC2 clients. Credentials come from the SDK default chain, so
existing aws sso login / aws configure / AWS_PROFILE / env / aws-vault
sessions keep working.
Verify auth via sts:GetCallerIdentity before the slow image build so a
logged-out user fails in seconds, not minutes. Upload via the S3
manager (concurrent multipart) with a native progress reader, log
[n/4] step lines, and bail on terminal import-snapshot failure states
instead of polling forever.

Capture the AWS Progress/StatusMessage fields and report them instead of
reprinting the full describe-import-snapshot-tasks JSON every 5s. On a
terminal, repaint one live percentage line; otherwise log one line per
phase change so CI stays terse.

Move the appliance/AMI build logic into tailscale.com/gokrazy/build so
Go callers (e.g. flash-appliance) can call it directly instead of
driving build.go over --json. build.go is now a thin flag wrapper; flags
and --json output are unchanged. Package-level state becomes a Builder
with an exported Config, ctx-first steps, and a Build one-shot.
