🐛 Fix bs-wrapper masking test failures, skip CookieStore tests

bs-wrapper.ts: ANSI escape codes from FORCE_COLOR broke failure
detection — the regex /\d+ failed \|/ didn't match colored output
like '9 failed\x1b[39m |'. Strip ANSI before matching.

cookieAccess.spec.ts: CookieStore API tests crashed with TypeError
when globalObject.cookieStore was undefined (Jasmine's pending()
inside setup() skipped the enclosing it(), but Vitest doesn't).
Added beforeEach ctx.skip for the CookieStore describe block.
