fixup: opencv 0.0.7 → 0.0.8 (template stderr fix; sha256 re-pinned)

v0.0.7's --template opencv scaffold used std::println(stderr, …) under a
bare `import std;` and did not compile (modules do not export the <cstdio>
stderr macro). opencv-m v0.0.8 fixes the template and adds a CI lint for the
class. No library-source or ABI change from 0.0.7.

- pkgs/o/opencv.lua: version 0.0.7 → 0.0.8 (all three OS blocks), sha256
  re-pinned to 0025f7a6…45cd8 (GLOBAL github archive == CN gitcode asset,
  both verified 11756053 bytes). Requires-mcpp note raised to >= 0.0.102
  (windows scan-deps cmdline, mcpp#261).
- tests/examples/opencv-module{,-dnn,-unifont}: consumer pins → 0.0.8.
