Lineage v0.1.0

Baseline stable master release for Lineage.

This release marks the point where Lineage can create and run local workflow packages with package validation, export/import safety, provider materialization, provider shims, diagnostics, and open-source project governance foundations.

This is not the full V1 distribution release yet. The V1 goal is tracked separately under Goal: Enable distribution: easy CLI installation, website-backed package publishing, package pulling, and unified receiver artifact processing.
