build(sdk/js): switch to tsup for dual CJS+ESM publish, drop sourcemaps

replace the two tsc invocations (node + browser) with a single tsup
build that emits both formats from one entry list.

- format: cjs (.js) and esm (.mjs); types as .d.ts and .d.mts
- splitting/sourcemap off; treeshake on
- exports use explicit \"types\"/\"import\"/\"require\" conditions per
  subpath so TypeScript picks .d.mts for ESM consumers and .d.ts for
  CommonJS, and runtime picks .mjs vs .js accordingly
- drop tsconfig.node.json and tsconfig.browser.json — tsup carries its
  own config, the root tsconfig.json is still used for typecheck
- drop .js.map / .d.ts.map outputs; the previous maps pointed at
  src/*.ts paths that the package did not ship, so they were dead weight

published package shape vs current 0.5.8-beta.1 on npm:

  files   : 60 → 27
  unpacked: 230 KB → 107 KB   (-54%)
  tarball :  57 KB →  23 KB   (-60%)

now also ships ESM (.mjs) — bundlers get tree-shaking, modern Node can
\`import\` natively; legacy \`require()\` still works through the .js
files.
