v0.72.0

[0.72.0] - 2026-07-28

✨ Highlights

This release introduces experimental build.steps as an alternative to build.script: each step is an isolated section of the build wrapper with its own if condition, interpreter, cwd, and env, so shell state no longer leaks between steps. It requires --experimental and is mutually exclusive with script. Recipes may now also carry a top-level $schema field for editor validation, and the process-execution layer gains reusable Runner and Session interfaces. Fixes cover case-insensitive RuntimeEnv lookups on Windows, deletion-only patches, Android DT_RUNPATH handling, and CEP-17 site-packages paths in SP_DIR.
