…v-mode banner - Rename eslint.config.js to eslint.config.mjs so Node treats the ESM config as a module (removes the MODULE_TYPELESS_PACKAGE_JSON warning) without adding "type": "module" (scripts/client.js stays CommonJS). - web-test-runner: pre-mark Lit's "dev-mode" warning as issued before any module loads, keeping the banner out of test output; scope test discovery to *Tests.ts.

flow-server-remove-client-engine) — merge after it. Non-draft; please review before merging.Re-created from #24956 after renaming the head branch
flow-client-ts-polish→feature/client-ts(the canonical branch for the full client TS migration). GitHub orphaned the original PR on rename.
