Test Release v0.0.1-test.2 (All Fixes)

Test release to validate the release pipeline and artifact generation.

All fixes included:

1. Fixed prism-loadtest module path (github.com/prism → github.com/jrepp/prism-data-layer)
2. Added prism-loadtest to Makefile build targets
3. Fixed Dockerfile to copy all pkg/ dependencies (not just pkg/plugin)

What gets built:

• ✅ Binaries: prism-admin, prismctl, prism-loadtest, pattern-launcher, plugin-watcher, prism-proxy (all platforms)
• ✅ Docker images: prism-admin, prismctl, pattern-launcher, plugin-watcher (all variants: scratch, distroless, alpine)

This is a pre-release for testing purposes.
