Allows user 'Snider' to trigger build jobs on PRs they author, in addition to the existing approval-based condition. Removes 'continue-on-error: true' from the release step in the upload-artifacts action to ensure failures are not ignored.
Split build jobs by architecture and OS in GitHub Actions workflows, add Docker and docs build jobs, and update artifact upload to create GitHub releases. Also update CPackConfig.cmake to use BUILD_VERSION for package versioning.
