Add multi-platform GitHub Actions workflow with manual trigger
Features: - workflow_dispatch trigger allows manual builds on any branch from GitHub UI - Matrix strategy builds for Linux (.so), macOS (.dylib), and Windows (.dll) - Platform selection via input parameter (specific platforms or 'all') - Automatic Swift toolchain setup for each platform - Generated libraries committed back to dlibs/ structure - Artifacts uploaded for manual download if needed Also updated: - Fixed existing ci.yml to use new dlibs/macos/ path structure - Removed redundant linux_setup.sh script (replaced by automated builds) Usage: Go to Actions tab → 'Build All Platforms' → Run workflow on desired branch
