fix(e2e): address failing byo e2e tests.

[Hweinstock]

Problem

See #1441 for failing test information.

Solution

• loosen regex and add result assertions.
• add more detailed logging on failures.
• avoid always using cdk main for byo tests.

Testing

ran e2e tests via scripts/run-e2e-local.sh.

Package Tarball

aws-agentcore-0.18.0.tgz

How to install

gh release download pr-1476-tarball --repo aws/agentcore-cli --pattern "*.tgz" --dir /tmp/pr-tarball
npm install -g /tmp/pr-tarball/aws-agentcore-0.18.0.tgz

[agentcore-cli-automation]

LGTM. Small note inline about the regex narrowing for the SigV4 rejection assertions — non-blocking, since the test setup makes the client-side fast-fail the only realistic path. The detailed-logging additions and the installCdkTarball/writeAwsTargets extraction are nice cleanups.
