This commit introduces the following updates:
- Adds an environment variable (`SOLSTICE_ALLOW_INSECURE`) to enable insecure TLS as a fallback for curl.
- Improves CA certificate handling and automatic installation on SunOS using IPS or pkgin.
- Extends fallback logic for repository fetching to cover scenarios with missing CA bundles.
- Updates Solstice job script dependencies to include `cmake`.
This commit improves the runner's functionality by adding:
- Detailed log streaming with request ID, stdout, and stderr line counts.
- Fallback mechanisms for repository fetch using HTTP archive when git commands fail.
- Enhanced error reporting for missing job scripts and reading errors.
- Updates to ensure compatibility with SunOS environments and non-interactive shells.
This commit updates the Solstice job script to install the Rust toolchain (`developer/rustc`) via the IPS package manager on Solaris-based systems (SunOS). It also adjusts the `ensure_rust` function to prioritize system package installation before falling back to `rustup`.
This commit introduces:
- Flexible runner URL configuration via `SOLSTICE_RUNNER_URL(S)` for cloud-init.
- Automated detection of OS-specific runner binaries during VM boot.
- Tasks for cross-building, serving, and orchestrating Solstice runners.
- End-to-end VM build flows for Linux and Illumos environments.
- Enhanced orchestration with multi-runner HTTP serving and log streaming.
