v0.0.8

Patch release.

• fix(template): the --template opencv scaffold did std::println(stderr, …) under a bare import std;; modules do not export the <cstdio> stderr macro, so the generated project failed to compile. The template now #include <cstdio> (matching examples/gray_pipeline), and CI gained a lint that fails a template TU touching stderr/stdout/stdin under import std; without .

No library source or ABI change from v0.0.7; the C++ module surface is identical. Verified end-to-end: mcpp new … --template opencv → build → run produces a grayscale PNG, and the dnn/unifont features build from a consumer.
