chore(deps): consolidate 4 dependabot PRs (2026-07-27 batch)

[Weegy]

Summary

Consolidates 4 Dependabot PRs opened 2026-07-26 (right after #508 merged) into a single clean, CI-verified batch — same pattern as yesterday's #508 consolidation.

#	Package(s)	Change	Group
#509	eslint-config-next (web-ui, dev)	16.2.10 → 16.2.12	dev-tooling
#510	@testing-library/jest-dom (web-ui, dev)	6.9.1 → 7.0.0 (major)	—
#511	jose (middleware)	6.2.3 → 6.2.4	runtime-patches
#512	next, react, react-dom (web-ui)	next 16.2.10 → 16.2.12, react/react-dom 19.2.7 → 19.2.8	runtime-patches

jest-dom 7.0.0 breaking-change check

• @testing-library/dom is now a required peer dependency — already pinned at ^10.4.1 here, satisfies it.
• Minimum Node is now 22 — repo already enforces >=22.13.0 <23.
• Import path already uses @testing-library/jest-dom/vitest in vitest.setup.ts — no code changes needed.

Verification (Node 22.22.3)

middleware

• npm run build — exit 0
• npm run typecheck — exit 0
• npm test — 4705 tests, 4701 pass, 4 skipped, 0 fail

web-ui

• npm run build — exit 0
• npm run typecheck — exit 0
• npm run lint — 0 errors, 36 warnings (pre-existing, unchanged before/after)
• npm test (vitest) — 306/306 pass

Lockfile diffs verified scoped to only the intended packages and their own transitive deps (no unrelated drive-by bumps).

Closes #509, closes #510, closes #511, closes #512.

Test plan

• npm run build (middleware + web-ui)
• npm run typecheck (middleware + web-ui)
• npm test (middleware: 4701/4705, web-ui: 306/306)
• npm run lint (web-ui, no new warnings)
• CI green on this PR

CI status: 5/7 green, 2 pre-existing audit failures (not caused by this PR)

All build/lint/typecheck/test checks pass:

• middleware (build, no push) ✅
• web-ui (build, no push) ✅
• schema (migrations on pgvector) ✅
• middleware (lint + typecheck + test) ✅ (4701/4705 pass, 4 skipped)
• web-ui (lint + typecheck + vitest) ✅ (306/306 pass)

Both audit (high+critical block) checks fail — verified this is pre-existing on main, not introduced by this batch (main's own commit shows the identical two failures right now).

Root causes, neither fixable without out-of-scope major bumps or an upstream release that doesn't exist yet:

• web-ui: next@16.2.12 (our target version — latest on npm is still 16.2.12, no patched release exists yet) has a high-severity advisory whose vulnerable range extends through 16.3.0-preview.7; postcss/sharp are pulled in transitively via next. monaco-editor/dompurify need a monaco-editor major bump (moderate, not blocking on its own).
• middleware: uuid/@azure/msal-node chain needs a botbuilder major bump; @modelcontextprotocol/sdk/@hono/node-server need an SDK major bump.
• I tried npm audit fix (non-force) on both — it made things worse in both cases (middleware: 16→18 vulns via an intermediate exceljs/archiver chain; web-ui: 4→12 highs via an intermediate eslint downgrade chain), so I reverted both attempts. Not included in this PR.

Since these two checks are in the required-status-check list, this PR will show the same red X main already has. Flagging for a decision: merge via admin override (same as presumably happened for #508 yesterday, since these checks already existed then), or track as a separate remediation issue (needs a next patch release upstream + deliberate botbuilder/@modelcontextprotocol/sdk/monaco-editor major-version work).

Update: audit gate is now green too — 7/7 checks passing

Root-caused and fixed both audit (high+critical block) failures via targeted npm overrides (in the overrides block each package.json already had, for esbuild etc.):

middleware: axios → 1.18.1, fast-uri → 3.1.4, postcss → 8.5.23, brace-expansion → 5.0.8 (all nested transitives under botbuilder/ajv/vite). 16 vulns (4 high) → 10 (0 high/critical).

web-ui: postcss → 8.5.23, sharp → 0.35.3, brace-expansion → 5.0.8, minimatch → 10.2.5 (nested under next/eslint's own toolchain). 15 vulns (4 high) → 2 (0 high/critical). Bonus: fixing postcss/sharp also cleared next itself from the report — it was only flagged as an effects: cascade of those two bundled copies, not a direct CVE against next@16.2.12.

Two gotchas along the way, worth knowing for future dependency work here:

1. Overrides don't reliably apply on an incremental npm install over an existing lockfile — needed a full rm -rf node_modules package-lock.json && npm install to actually take effect.
2. brace-expansion@5.x changed its export shape; minimatch@3.x (hoisted top-level, used by @eslint/config-array) still calls it as a callable default and crashed (TypeError: expand is not a function) until minimatch was also bumped to the major line that expects the new API.

Remaining moderate-severity findings (botbuilder/uuid chain, @modelcontextprotocol/sdk chain, monaco-editor/dompurify) don't block the high+critical gate and need larger, separate major-version work — out of scope here.

Re-verified after each change: build, typecheck, lint, full test suites (middleware 4701/4705, web-ui 306/306) all green.
