GitHub Actions

Actions can now reference themselves via self-repository action reference syntax, the effective cache mode is exposed to steps through ACTIONS_CACHE_MODE, and a new GITHUB_ARTIFACTS environment files feature is supported. Also fixed canceled background steps no longer impacting job results, session cleanup on errors, and ephemeral runner exit on broker acknowledge job-not-found.

Expanded commit hash regex to support SHA-256 (64-character) hashes. Added support for Ubuntu 26.04 with updated libraries (liblttng-ust1t64, libicu77-80). Includes background step execution engine infrastructure, debugger console improvements, and updated dependencies including Docker v29.5.2, .NET SDK 8.0.421, and Node versions.

Background step execution engine infrastructure is now in place, enabling deferred step control and execution within job containers. Added support for Ubuntu 26.04 with required libraries (liblttng-ust1t64, libicu77-80), expanded commit hash regex to support SHA-256 hashes, and fixed action download 403 errors to no longer retry.
