Test automatic IDE runtime builds

[miki3421]

What changed

• add a neutral ops ide deploy runtime-profile fixture
• deploy an action that imports a dependency absent from the base runtime
• verify the generated blackbox image and action invocation
• repeat the deploy and assert that no additional builder Job is created
• include the test in tests/all.sh

Why

The automatic deployer spans tasks, the system API, BuildKit, the private registry, the node runtime, and action invocation. Unit tests alone do not protect that contract.

Impact

The integration suite now detects regressions in automatic runtime builds and cache reuse on supported Kubernetes targets.

This draft depends on the coordinated openserverless-task, openserverless-admin-api, openserverless-operator, and openserverless-runtimes changes.

Validation

• shell syntax and git diff --check
• complete test script passed on ARM64 Kind/Lima
• complete test script passed on ARM64 K3s without Docker
• dependency version, action invocation, and cached second deploy verified
