ci: shorten pull request test runs

[fengmk2]

Each pull request runs the full test suite on nine platform and Node.js combinations. Repeated test work and runner waits delay feedback.

Run Node.js 22, 24, and 26 on Linux. Run Node.js 24 on macOS and Windows. Split the four slower combinations into two test groups. Keep all nine combinations for merge groups, next pushes, manual runs, and PR runs with the ci:full label.

The following table compares the measured GitHub Actions runs for ordinary PR feedback.

Metric	Before	After	Reduction
CI elapsed time	20m 49s	13m 10s	36.7%
Total runner execution time	151.68 minutes	86.78 minutes	42.8%

Elapsed time includes queue delays. Runner minutes exclude queue delays and the separate E2E workflow. The baseline had a CLI failure; all main-suite jobs passed. This is a single-run comparison, so queue delays and cache state can affect later results.

Use one exact Node.js version for coverage. Check that coverage groups contain every test file exactly once before merging their reports. Save durations, retries, and resolved worker settings as artifacts. Make done reject failed, cancelled, missing, or unexpectedly skipped checks.

Replace fixed schedule readiness waits with checks for the expected condition. Use available inspector ports and distinguish --inspect-port from --inspect in the CLI.

Update codecov/codecov-action to v5.5.5 so uploads use the current signing-key endpoint.

Summary by CodeRabbit

• Bug Fixes

  • Node.js inspector options are now recognized correctly when similar options are already configured, improving debug and development command behavior.

• CI

  • Pull request checks now use a tailored test matrix, with shard results validated before coverage reports are merged.
  • CI checks also run for reopened pull requests and merge queue events.

• Documentation

  • Updated CI workflow and performance documentation to reflect the current test matrix, coverage reporting, and parallel test metrics.
