Add GitHub Copilot Developer Skills for OVMS

[rasapala]

🛠 Summary

This PR introduces four GitHub Copilot skill files under .github/skills/ to streamline common developer workflows when working on the OpenVINO Model Server codebase.

New Skills

build-bazel-target
Triggers: bazel build, build ovms, //src:ovms
Purpose: Build any Bazel target inside the -build Docker container

build-builder-image
Triggers: make docker_build, rebuild -build image, make ovms_builder_image
Purpose: Build or rebuild the OVMS -build Docker image via the Makefile

run-single-gtest
Triggers: run this test, bazel test --test_filter, ovms_test
Purpose: Run or re-run a single gtest fixture/test case inside the container

run-make-style
Triggers: run make style, cpplint, clang-format-check, cppclean
Purpose: Run code-style and lint checks via make style

Details

• Each skill file is a self-contained Markdown instruction document with YAML frontmatter describing when it should be invoked by Copilot.
• Skills cover container reuse/creation, proxy forwarding (http_proxy/https_proxy/no_proxy), Red Hat distro support (--//:distro=redhat), and common error-reading steps (e.g. bazel-testlogs).
• Skills include optional USER DEFAULTS placeholder blocks so individual developers can hardcode a preferred build container, target list, or distro without modifying the shared workflow logic.
• Skills are auto-discovered by GitHub Copilot via YAML frontmatter in each file — no additional wiring is required. Copilot matches the skill to user requests based on the trigger phrases listed in each skill's description field.

Pull request overview

This PR adds four GitHub Copilot “skill” instruction documents under .github/skills/ to standardize common OVMS developer workflows (Bazel builds/tests in the -build container, builder image rebuilds via Make, and host-side style checks).

Changes:

• Add a skill for building arbitrary Bazel targets inside a user-specified -build Docker container.
• Add a skill for rebuilding the OVMS -build Docker image via make ovms_builder_image / make docker_build with common flags and proxy handling.
• Add skills for (a) running a single filtered C++ gtest via Bazel and (b) running make style and related lint/format targets.
