CI update: new runner test

[gneeri]

Note

Medium Risk
CI/release pipelines are reworked to rely on pre-provisioned self-hosted runners and stricter environment validation, which can break builds/releases if runner setup or PATH/env assumptions are wrong.

Overview
Moves the CI workflow’s Linux job to a self-hosted GCP runner and replaces in-job provisioning with preflight validation of the Rust toolchain and required system libraries; macOS remains using actions-rs/toolchain/rust-cache.

Refactors test execution to generate test.log consistently (Linux serializes tests via RUST_TEST_THREADS=1) and only posts the PR test-summary comment when a log exists.

Extends the Release workflow with a Windows self-hosted build-and-test job (also runnable via workflow_dispatch against an arbitrary ref) and gates release/publish jobs to push events only. Adds strawberryperl to Windows dependency setup.

Adds infra provisioning scripts: infra/scripts/bootstrap-linux-runner.sh, infra/scripts/bootstrap-windows-runner.ps1, and infra/scripts/configure-linux-runner-service-env.sh to standardize self-hosted runner setup and deterministic PATH/env configuration.

Autofix Details

Bugbot Autofix prepared fixes for both issues found in the latest run.

• ✅ Fixed: VS installer exit code 3010 incorrectly treated as failure
  • The Visual Studio installer exit-code check now accepts both 0 and 3010 so reboot-required success no longer aborts bootstrap.
• ✅ Fixed: Native command failures silently ignored in bootstrap script
  • Added explicit $LASTEXITCODE checks with throws after rustup component install, git clone, vcpkg bootstrap, and each vcpkg install command.
