chore(web): format-gate the ungated first-party TS/JS (server/, vite.config.ts, scripts/) (#1788)

* chore(web): format-gate the ungated first-party TS/JS (#1778)

Prettier only covered core/ and each client's src/, leaving the web Node
backend (clients/web/server/**), web top-level configs (vite.config.ts,
tsup.runner.config.ts, eslint.config.js, ...), and the root build/verify
tooling (scripts/**/*.mjs) ungated — so their formatting was never checked
by validate/CI. eslint already reached these via `eslint .`, so this is a
prettier-only gap.

- clients/web format/format:check now cover src, server, and top-level
  *.{ts,js}, not just src.
- New root format:scripts / format:check:scripts for scripts/**/*.mjs,
  folded into the root format and into validate:core.
- Normalized the newly-covered files with prettier --write (pure
  formatting; no runtime change).

Closes #1778

* chore: future-proof the scripts format glob (#1778 review)

Widen format:scripts / format:check:scripts from "scripts/**/*.mjs" to
"scripts/**/*.{mjs,js,cjs,ts}" so a future non-.mjs file under scripts/
is auto-gated, matching the future-proof glob style clients/web now uses.
A brace glob is a single pattern, so prettier does not error on the
unmatched branches. Addresses observation #2 from the PR #1788 review.

* docs: sync AGENTS.md scripts glob after the widening (#1788 review r2)

d86d8f7 widened the scripts glob to {mjs,js,cjs,ts} and updated the
validate:core bullet, but the format bullet at AGENTS.md:217 still said
scripts/**/*.mjs. Bring it in line so the two mentions agree.

 ### Mandatory pre-push gate
-- ALWAYS do `npm run format` before committing — the **root** `format` auto-fixes `core/` (`format:core`) and every client's scope in one shot. `validate` runs `format:check` (the non-fixing variant, including `format:check:core`) and will fail in CI on any unformatted file, so always run the auto-fixer first rather than letting `format:check` catch it.
+- ALWAYS do `npm run format` before committing — the **root** `format` auto-fixes `core/` (`format:core`), the root `scripts/**/*.{mjs,js,cjs,ts}` (`format:scripts`), and every client's scope in one shot. `validate` runs `format:check` (the non-fixing variant, including `format:check:core` and `format:check:scripts`) and will fail in CI on any unformatted file, so always run the auto-fixer first rather than letting `format:check` catch it.
 - **`npm run ci` is the mandatory pre-push command** — it mirrors `.github/workflows/main.yml` (minus `npm install`): `validate` → `coverage` → `verify:build-gate` (the #1769 browser-externalized-builtin build gate) → `smoke` → Storybook play-function tests (installs Playwright chromium if needed). It now runs **`npm run coverage`**, the per-file ≥90 gate (lines/statements/functions/branches) that CI enforces — so `npm run ci` is a true superset of GitHub CI, and passing it locally means CI's gates will pass. Expect several minutes. **`npm run validate`** remains the fast inner-loop check during development (unit tests only — no coverage gate, no smoke, no Storybook), but it is **NOT** an acceptable substitute for `npm run ci` before pushing: `validate` runs `test`, not `test:coverage`, so it does **zero** coverage gating. Skipping the gate is how a push passes every fast local check and still fails CI (this exact gap broke PR #1601 on a function-coverage regression).
 - ALWAYS do `npm run format` before committing, then **`npm run ci`** before pushing. From the repo root, `validate` runs the **`core/` gate first** (`validate:core`) and then chains the four per-client validations (`validate:web` → `validate:cli` → `validate:tui` → `validate:launcher`); each client delegates to its own `npm run validate` in its own folder (no coverage — fast). Every client is self-validating and the top level just chains them, building each client's bundle along the way (no cross-client build dependencies).
-  - **`validate:core` is the shared-code format + lint gate (#1689).** Each client's `prettier`/`eslint` is scoped to its own dir, so nothing reached `core/` before — `validate:core` closes that: it runs `format:check:core` (`prettier --check "core/**/*.{ts,tsx}"`) + `lint:core` (`eslint "core/**/*.{ts,tsx}"` via the **root** `eslint.config.js`). Use `npm run format:core` to auto-fix. The root carries prettier/eslint as devDependencies for this; `core/` is isomorphic (browser + Node globals, no JSX today — the `{ts,tsx}` glob future-proofs against a `core/**/*.tsx`). The root `eslint.config.js` honors an `_`-prefix as the intentionally-unused marker (`argsIgnorePattern`/`varsIgnorePattern`/`caughtErrorsIgnorePattern: '^_'`).
+  - **`validate:core` is the root-owned format + lint gate (#1689, widened in #1778).** Each client's `prettier`/`eslint` is scoped to its own dir, so nothing reached `core/` or the root `scripts/` before — `validate:core` closes that: it runs `format:check:core` (`prettier --check "core/**/*.{ts,tsx}"`) + `format:check:scripts` (`prettier --check "scripts/**/*.{mjs,js,cjs,ts}"`, the root build/verify tooling — #1778; a brace glob so a future non-`.mjs` script is auto-included) + `lint:core` (`eslint "core/**/*.{ts,tsx}"` via the **root** `eslint.config.js`). Use `npm run format:core` / `npm run format:scripts` to auto-fix (both folded into the root `format`). The `scripts/` gate is prettier-only — the root has no eslint config for `.mjs`. The root carries prettier/eslint as devDependencies for this; `core/` is isomorphic (browser + Node globals, no JSX today — the `{ts,tsx}` glob future-proofs against a `core/**/*.tsx`). The root `eslint.config.js` honors an `_`-prefix as the intentionally-unused marker (`argsIgnorePattern`/`varsIgnorePattern`/`caughtErrorsIgnorePattern: '^_'`).
   - **cli and tui now typecheck their `src` (#1689).** Their `build`/`test` run through esbuild (no type check), so each has a `typecheck` script (`tsc --noEmit -p tsconfig.json`) folded into `validate`. Their `tsconfig.json` matches `clients/web/tsconfig.app.json`'s module/lib *resolution* options — DOM lib, `moduleResolution: bundler`, and **no** `noUncheckedIndexedAccess` (web's app config does not extend `tsconfig.base`, so re-enabling it would surface `core/` issues web never gates) — so the imported `core/` sources are validated the same way web validates them. It does **not** mirror web's extra strictness flags (`noUnusedLocals`, `verbatimModuleSyntax`, ES2023 target, …), so cli/tui's own `src` is checked slightly more loosely than web's. `core/` itself still typechecks through web's `tsc -b`.
-  - The one CLI nuance: `clients/cli`'s out-of-process `e2e.test.ts` spawns the built binary, so its `test` **builds first** via `pretest` (`test-servers:build && build`). To avoid building it twice, `clients/cli`'s `validate` folds that in — it is `format:check && lint && typecheck && test` with **no** separate `build` step (the other clients, whose tests don't spawn their bundle, keep an explicit `build`). `validate:web`/`validate:tui`/`validate:launcher` are the uniform `format:check && lint && (typecheck &&) build && test`.

   - **`npm run coverage`** is the per-file ≥90 gate and is now part of `npm run ci` — never treat it as optional before a push. It supersedes the old standalone `test:integration` step: web's `test:coverage` runs the `unit` **and** `integration` projects under v8 instrumentation, so `coverage` both enforces the ≥90 gate and exercises the same web integration paths CI covers.
 - **`smoke` is NOT part of `validate`** — it is included in `npm run ci`. It runs `smoke:launcher` (`--help` dispatch) plus the prod `smoke:cli` / `smoke:tui` / `smoke:web` / `smoke:web:browser`, and contains **no build commands** — it assumes the cli/tui/launcher bundles already exist (a full `validate` builds them; `smoke:web` builds `clients/web/dist` on demand). CI runs `validate`, then the `coverage` gate (which also covers the web integration project), then `verify:build-gate` (the #1769 build gate — see below), then `smoke` (with Playwright chromium installed just before it, since `smoke:web:browser` needs it). GitHub CI runs this same chain as separate workflow steps, with the Storybook play-function tests last (see below).
 - `smoke:launcher` (`scripts/smoke-launcher.mjs`) runs the built launcher with `--help`, `--cli --help`, and `--tui --help`, asserting each exits 0 and prints that mode's usage banner (which also proves the launcher resolved and loaded the right client build). It's the cheap dispatch check before the heavier prod smokes below.
