perf(build): bundle to a single minified file (tsup) — v1.81.0, ~66kB → ~41kB

[justadev-afk]

What & why

twisted is a thin API wrapper, so the published artifact should be small. This PR replaces the multi‑file tsc output with a single minified bundle built by tsup, shrinking what consumers download and the file count dramatically.

Builds on top of the 1.80.x dependency cleanup already on master (axios/lodash/dotenv/http-status-codes/uuid removed — promise-queue is the only runtime dependency).

Changes

• Bundle with tsup → dist/ is now just index.js (minified CJS) + a rolled‑up index.d.ts. The TFT static JSON is inlined; promise-queue stays external.
• target es6 → es2021 → async/await, ?. and ?? emit natively, removing the __awaiter/__generator helpers that were duplicated across ~20 files. (es2021, not es2022, to avoid flipping useDefineForClassFields.) Already require Node ≥ 18.
• JS is minified, but the rolled‑up .d.ts keeps its JSDoc → smaller code, hover/IntelliSense docs preserved.
• yarn build runs tsc --noEmit first so type errors still fail the build; added a typecheck script.
• Stop publishing yarn.lock — useless to consumers, only bloats the tarball.

Expected bundle size

	Packed (npm)	Unpacked	Files
1.80.x (current)	~66 kB	~311 kB	349
1.81.0 (this PR)	~41 kB	~166 kB	5

dist/index.js ≈ 41 kB minified (~13 kB gzipped); dist/index.d.ts ≈ 110 kB (the bulk of the tarball — JSDoc kept on purpose for DX). Net: ~38% smaller download, 349 → 5 files.

⚠️ Breaking change → minor bump 1.81.0

Deep imports such as twisted/dist/errors or twisted/dist/apis/... no longer resolve. Import from the package root instead — the barrel re‑exports apis, errors, Constants and Dto:

import { LolApi, Constants, GenericError } from 'twisted'

Verification

• tsc --noEmit (typecheck) + tsup build ✅ · eslint ✅ · 42/42 jest tests ✅
• Runtime smoke against the built dist/index.js (Account → Summoner → Match‑V5 chain + TFT StaticFiles from the inlined JSON) ✅
• Consumer type‑check against dist/index.d.ts (API classes, Constants values, method return types, error classes) ✅

Merging publishes 1.81.0 to npm via the (now resilient) Deploy workflow.
