perf: Fix worker test execution excessive delay

[nev21]

• Switch worker tests to mocha + karma-typescript with adapter/runner flow and suite-aware reporting.
• Normalize browser/worker test globs and coverage exclusions to reduce noise.
• Add environment sanity tests for browser/node/worker and rename iterable expect test to .test.ts.
• Update test scripts, remove rollup preprocessor usage, and align dev deps to the new setup.
• Minor config tweaks (typedoc grouping, tsconfig settings).

Pull request overview

Updates the test infrastructure to eliminate excessive delays in worker test execution by switching worker runs to a mocha + karma-typescript flow with a custom adapter/runner, while also normalizing test file globs and coverage exclusions across node/browser/worker.

Changes:

• Reworks worker Karma configs to use mocha + karma-typescript and a custom worker adapter/runner for suite-aware reporting.
• Normalizes node/browser/worker test globs and coverage exclusions; adds environment sanity tests.
• Adjusts package scripts/dev-deps and minor config tweaks (TypeDoc grouping, tsconfig).
