Pull request overview

This PR optimizes worker test execution performance by replacing the slow karma-mocha-webworker + rollup setup with a faster karma-typescript-based approach using custom worker adapter and runner scripts.

Changes:

• Switched worker tests from karma-mocha-webworker + rollup preprocessor to mocha + karma-typescript with custom worker adapter/runner
• Added environment-specific test files to validate test execution contexts (browser, node, worker)
• Removed unnecessary dependencies (karma-coverage, karma-coverage-istanbul-reporter, karma-mocha-webworker, karma-rollup-preprocessor) and removed NODE_OPTIONS memory limit workaround
