- onUnhandledRequest was renamed to onUnhandledFrame, which fixes the type-check (lint CI job) failure - scope the contractor schema-version handlers to their own country so a request from a neighbouring test can't satisfy them - assert the job-title abort on the signal passed to fetch, since msw v3 no longer reflects the client abort on request.signal in this path Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

Major MSW bump can change request matching and interception across the test suite; MSW 3 requires Node ≥22.12 while
package.jsonstill allows Node ≥20, which may break installs or tests on older Node in CI.Overview
Upgrades the MSW dev dependency from 2.15.0 to 3.0.2, with lockfile updates for MSW’s new dependency graph (e.g.
@msw/url, updated interceptors, Node ≥22.12 for MSW).Test harness changes for MSW v3:
server.listennow usesonUnhandledFrameinstead ofonUnhandledRequest. Contractor onboarding schema tests use explicit country codes in handler URLs (PRT/DEU/USA) instead of*wildcards. The job-title eligibility abort test asserts cancellation viafetchspy +AbortSignalrather thanrequest.signalinside the MSW handler.Reviewed by Cursor Bugbot for commit 80c60bf.
