fix(versioning): embed version via rustc-env; drop OUT_DIR include

- Make version part of rustc inputs (sccache-friendly) to prevent stale
  0.2.59 binaries appearing in newer releases.
- Stop generating code_version.rs and include!(OUT_DIR/…).
- CI: broaden release workflow paths-ignore to all workflows.
- Docs: adjust changelog header + tip block.
- Issue template: update example model list.
