Subject: [PATCH] build(js-legacy): upgrade TypeScript to 6.0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bump typescript to ^6.0.3 in clients/js-legacy and adjust the tsc-based
build for TS6:

- tsconfig.base.json: add "ignoreDeprecations": "6.0" (the node10/"Node"
  module resolution is deprecated in TS6, TS5107) and "types": ["node"]
  so Buffer/http/https globals from @types/node resolve (TS2591 under the
  classic resolver).
- tsconfig.cjs.json / tsconfig.esm.json: add "rootDir": "./src" — TS6
  requires an explicit rootDir for these composite projects (TS5011).
- tsconfig.json: set "types": ["node", "mocha"] so the test build still
  sees mocha's globals after the base "types" narrowing.

Module resolution is left as-is and no lib override is added; only the
options TS6 actually requires were changed.

Verified locally with typescript@6.0.3: `pnpm build` (tsc --build),
`pnpm lint` (eslint), and `pnpm test` (mocha, 7 passing) all pass.
