Matt 4879b17cff feat(deps): Next 15 → 16 (proxy.ts rename + native flat ESLint config)
Applied @next/codemod migrations:
- middleware-to-proxy: src/middleware.ts → src/proxy.ts + function rename
- remove-experimental-ppr: no hits
- remove-unstable-prefix: no hits

tsconfig.json picked up Next 16's autofixes:
- jsx: 'preserve' → 'react-jsx'
- include .next/dev/types/**/*.ts (dev-mode route types)
- next-env.d.ts: triple-slash reference → ES import (TS 6 / Next 16 style)

eslint-config-next@16 ships a native flat config, so dropped the
@eslint/eslintrc + FlatCompat shim. eslint.config.mjs now imports
eslint-config-next/core-web-vitals + eslint-config-prettier/flat
directly.

Note on ESLint 10: bumped + reverted. eslint-config-next@16 still
has a transitive eslint-plugin-react@7 that uses the eslint-9
context API (getFilename on context); breaks under eslint 10.
Audit anticipated lockstep — but the transitive isn't ready yet.
Holding at eslint 9.x until upstream lands. Tracked in BACKLOG.

React Compiler safety rules (react-hooks v7) shipped with config-
next 16 surfaced ~89 legitimate findings (set-state-in-effect,
ref-during-render, immutability). Demoted the new rules to `warn`
so the codebase isn't blocked; triage tracked in BACKLOG §G.

Verified: tsc 0 errors, eslint 0 errors / 105 warnings (89 new
Compiler-rule warns + 16 pre-existing), next build clean, custom
server build clean, vitest 1315/1315.
