Replace the harnesses' Deno APIs and import maps with Node.js built-ins and explicit npm dependencies. Prepare Deno caches only when the selected test target needs them, so npm-based workflows can run without Deno while keeping the existing runtime matrices.
Move subprocess handling into a shared helper so cancellation waits for the process tree to exit and command failures propagate to the final exit status, preventing leaked servers and false passes. Update contributor guidance to match the new workflow.
Use Node.js for repository scripts and development harnesses so selected
Node.js targets work without Deno or its import map. Keep Deno applications
in the existing test matrices.
Propagate subprocess failures and preserve signal exit statuses after
cleanup. Add regression tests, three-platform CI coverage, and updated
contributor instructions.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Development scripts and test harnesses now run on Node.js. Shared process utilities support subprocess execution and cleanup. Deno remains available for selected test targets. Task configuration, CI workflows, dependencies, and runtime instructions reflect this split.
Changes: Node.js tooling and maintenance scripts
Layer / File(s)
Summary
Shared process tooling and maintenance scripts scripts/tooling_*.ts, scripts/check_*.ts, scripts/generate_packages_table.ts, scripts/sponsors.ts, related tests
Shared filesystem, entry-point, and process helpers support Node-based maintenance scripts. The scripts and tests use Node APIs. Process helpers capture command output and handle signal-driven cleanup.
The initializer harness uses Node to generate test projects and run CLI lookups. It combines generation and lookup results and handles cancellation, process cleanup, and port release. Tests cover these paths and platform-specific behavior.
Example, monitoring, and compatibility harnesses examples/test-examples/*, examples/monitoring/*, packages/astro/compat/run.ts, packages/sveltekit/compat/run.ts
These harnesses use Node APIs and shared process tooling. The example runner updates readiness polling, output draining, cancellation, and cleanup.
Mise tasks and CI workflows invoke Node-based tooling and omit Deno cache setup where it is not needed. Dependency mappings, workspace configuration, and runtime instructions are updated.

Explanation
The PR satisfies the coding requirements in #1283. The scripts and harnesses use Node.js APIs, explicit npm dependencies, and Node TypeScript execution. mise.toml keeps Deno cache setup only on Deno-dependent targets. scripts/test_tooling_no_deno.mjs verifies Node-only tasks without a Deno executable or cache. Example, initializer, and framework coverage remains. tooling_process.ts and the added tests cover exit status propagation, cancellation, process-tree cleanup, output draining, Windows handling, and signal exit codes. The initializer tests also cover empty and filtered matrices.
Full details: Out of Scope Changes check
Explanation
The changes remain within #1283. Workflow and contributor-documentation changes support the Node.js harness workflow and conditional Deno caching. The shared process helper and regression tests implement the required exit-code, cancellation, cleanup, and platform behavior. Initializer runtime-selection and aggregate-result changes preserve target coverage and prevent false success. No unrelated product feature or independent change is established by the evidence.

Review comments at @deno.json:
- Line 98: Add an explicit TypeScript type directive to the cross-spawn import
in tooling_process.ts, pointing to the @types/cross-spawn declarations so Deno
can type-check the import with nodeModulesDir set to none.
Review comments at @scripts/tooling_main.ts:
- Around line 6-9: Update isMain to compare canonical real paths for the entry
point and module URL, retaining a safe fallback when canonicalization fails. In
packages/init/src/test/mod.ts, replace the duplicated entry-point comparison
with the shared isMain(import.meta.url) helper and remove imports made
unnecessary by that change.
Review comments at @scripts/tooling_process.ts:
- Around line 30-40: Update onSignal to exit immediately with the appropriate
signal-derived code when stopping is already true; preserve the existing cleanup
flow and exit behavior for the first signal.

Compare canonical entry and module paths so Node's symlink resolution
does not silently skip script execution. Reuse the shared check in the
initializer harness and retain the fallback for unavailable paths.
Cover symlinked script files and directories, including the initializer
entry point, with regression tests that fail before the fix.

Keep the first signal's awaited cleanup, but let a second SIGINT or
SIGTERM exit immediately with its conventional status. A hanging
resource cleanup must not leave every later interruption ignored.
Test real repeated signals while a registered cleanup never settles.

The Windows bootstrap failed because the runtime-check fixture relied on
.cmd stubs writing a log. Substitute Node executable probes in the child
fixture so observing runtime checks does not depend on shell shims.
Assert that npm matrix cases skip both probes and the public CLI runs
both, without changing the initializer's runtime checks.

Return valid version strings from both probes and await a successful

filterOptions() can reject every selected tuple, such as next/npm/denokv/in-process, because denokv supports only deno. This leaves dirs empty. dirs.every(Boolean) and the empty lookup aggregate both return true, so the CLI exits successfully without running a test. The same false success occurs when lookup.ts skips every generated directory.
