* 📦 chore: Upgrade react-router-dom to v7.18.2 (security)
Fixes GHSA-wrjc-x8rr-h8h6 (open redirect via backslash in Link/useNavigate,
CVE-2025-68470 bypass) and GHSA-337j-9hxr-rhxg (deserializeErrors constructor
injection). Neither has a 6.x patch; v7's react-router-dom is a shim
re-exporting react-router, so all existing imports work unchanged.
- vite manualChunks: match react-router so the routing chunk still captures
the router (v7 moves all code out of the react-router-dom package)
- jest: add test/polyfills.js (TextEncoder/TextDecoder + minimal Request);
v7's CJS bundle constructs TextEncoder at module scope and builds a Request
per navigation, neither exists in jsdom
- auth specs: v7 types drop the synthetic default export; use a namespace
import and mark the mock factory __esModule so the useOutletContext spy
patches the object components actually read
- isSafeRedirect: reject backslashes as defense in depth for the same
open-redirect class the router patch addresses
* 📦 chore: Regenerate stale bun.lock
bun.lock predated months of package.json drift and still pinned
react-router 6.30.3. Regenerated with bun install --lockfile-only so bun
installs match current manifests, including react-router 7.18.2.
* 🗂️ fix: Commit project-chip URL updates synchronously under router v7
v7 wraps router state updates in React.startTransition unconditionally, so
the chip's paired updates tear: the conversation draft (Recoil) commits
synchronously while the ?projectId removal defers. ChatRoute's
draftProjectMismatch re-init sees draft != URL in that window and restores
the removed project. The flushSync navigate option commits both in one pass,
matching v6 ordering. Caught by the projects e2e specs.
* 🧹 chore: Drop unused banner-query spy variable in Registration spec
Pre-existing warning, but the changed-files eslint gate runs with
--max-warnings=0 so it blocks this PR. The spy call stays; only the
never-read variable goes.
