Scaffold core/OBS-adapter split, prove CMake toolchain, add 3-platform CI

First pass on the streamer-tools OBS camera plugin: a minimal but real CMake project matching the design doc's core-library/OBS-adapter split (docs/superpowers/specs/2026-09-06-obs-camera-plugin-design.md in the streamer-tools repo). No LiveKit FFI integration yet -- this proves the toolchain works. - core/: dependency-free C++17 library (no OBS dependency), unit tested via CTest with no external test framework. - obs-adapter/: adapted from obsproject/obs-plugintemplate (commit 3e7d7ac, 2025-12-09). Registers a real, stubbed OBS source type; builds as a genuine dynamically-linked OBS module against Ubuntu's system libobs-dev (confirmed via ldd/nm, not a fake stand-in). - Simpler hand-written top-level CMakeLists.txt in place of the template's full buildspec-driven bootstrap (which downloads full OBS source + prebuilt deps) -- find_package(libobs) alone is enough on Linux; falls back to core-library-only when libobs isn't found (expected on macOS/Windows CI for now). - .gitea/workflows/build.yml: 3-platform matrix (ubuntu-latest, macos-latest, windows-latest) matching the runners confirmed available to this repo under the CyberCoveLLC org.
