test(e2e): cover harness happy path

[Hweinstock]

Summary

• add table-driven harness happy-path e2e coverage
• cover managed, disabled, and semantic memory configurations
• verify a custom system prompt through the remote invocation transcript
• remove every harness and deploy the empty project

Verification

• bun test — 3,559 passed, 0 failed
• bun run typecheck
• bun run lint:check
• bun run format:check
• bun run secrets:check
• bun run compile
• harness e2e against a dev account — 14 passed, 0 failed in 592.45s, including final stack teardown

The successful e2e run used the schema-v2 CDK CI tarball because the base branch pins
@aws/agentcore-cdk@1.0.0-rc.2, which is not currently published to npm. A post-rebase
rerun stops during project creation at that package installation and creates no AWS
resources.

Testing instructions

bun install --frozen-lockfile
bun run compile
export AGENTCORE_CLI_PATH="$PWD/dist/bin/agentcore-linux-x64"
export AWS_REGION=us-east-1
bun run test:e2e -- e2eTest/project/harness.test.ts

Reproduction

Before this change, e2eTest/project/ covered runtime templates but did not exercise
the harness add, deploy, remote invoke, remove, and teardown lifecycle.

Spec

Add e2eTest/project/harness.test.ts with test cases defined by a harness name,
additional add flags, and additional invoke flags. Cover only two to three memory
settings and one custom-system-prompt harness. Add the harnesses to an empty project,
deploy them, invoke them remotely, remove them, and deploy the empty project.

lets move the timeouts to a central timeouts.ts so that these are shared with other tests.

lets do a remove all here.
