* refactor(browser): share engine adapters for Chromium and Lightpanda
Refresh signed stack identities without changing any source tree.
Previous signed head: bed85c558d
PR06 CI tested stale synthetic merge22409995, whose main base80c3c742 predates Peter Steinberger's canonical static-validation fix82411a34. Fresh synchronization must check the repaired merge context; neither old failed CI nor old passing runtime proof is relabeled. Preserve every source/test/dependency blob and previously qualified registry/catalog fixture correction.
* improve(browser): default managed Chromium to efficient headless launches

* test(agents): retain canonical restored-run settlement fixture
* test(agents): preserve upstream requester-disposal completion ordering
* fix(browser): preserve shared Chromium discovery and Lightpanda lifecycle
* fix(browser): align lightweight image integration
Preserve the current shared browser discovery helper and renderer fixtures after baseline integration. Leave Lightpanda resource ceilings with operators and keep selected-image proof wording version neutral.
