Add opt-in support for enumerating and evaluating JavaScript inside a page's dedicated Web Workers, so agents can inspect off-main-thread app logic (e.g. Neo.mjs). The feature is gated behind a new --experimentalWorkers flag and is off by default, so worker execution contexts are never enumerated unless explicitly requested and the baseline token usage is unchanged. - Add list_dedicated_workers tool to list a page's dedicated workers and assign each a stable worker id. - Add an optional workerId argument to evaluate_script that resolves the target through the existing Page | Frame | WebWorker union, mirroring the existing serviceWorkerId path.

Adds opt-in support for evaluating JavaScript inside a page's dedicated Web Workers, so agents can reach off-main-thread application logic (e.g. Neo.mjs).
Everything is gated behind a new
--experimentalWorkersflag and off by default. Worker contexts are never enumerated unless explicitly requested, so baseline token usage is unchanged.list_dedicated_workerslists the selected page's dedicated workers and assigns each a stable worker id.evaluate_scriptgains an optionalworkerIdargument that resolves the target through the existingPage | Frame | WebWorkerunion, mirroring the existingserviceWorkerIdpath (same mutual-exclusivity and no-element-args guards).Shared workers (#317) are intentionally left out of scope.
Tests cover both tools and the new evaluate path.
build,typecheck,eslint,prettier, andnpm run gen(docs + CLI reference) all run clean.Refs #316
