[PR] fix(computer-use): enforce JSON line UTF-8 byte limit [maka]

["liuxiaocs7 (via GitHub)" <gi...@apache.org>]

liuxiaocs7 opened a new pull request, #4953:
URL: https://github.com/apache/maka/pull/4953

   ## Summary
   
   Measure the accumulated stdio JSON-line tail in UTF-8 bytes before comparing it with `maxBufferBytes`. This prevents multibyte executor output from retaining substantially more memory than the negotiated byte budget.
   
   Add focused regression coverage for an over-limit multibyte tail, an exact-limit multibyte tail, and unchanged ASCII behavior across chunks.
   
   Fixes #4952
   
   ## Verification
   
   - `npm --workspace @maka/computer-use run build` — passed
   - `node --test packages/computer-use/dist/__tests__/stdio-json-rpc.test.js` — 3/3 passed
   - `npm --workspace @maka/computer-use run test:dist` — 117/117 passed
   - `npm --workspace @maka/computer-use run typecheck` — passed
   - `npm run build` — passed
   - `npm run typecheck` — passed after rebuilding workspace declaration output
   - `npm run lint` — passed
   - `npm run format:check` — passed
   - `npm test` — the changed tests passed, but the repository-wide parallel run failed in unrelated timing-sensitive PTY/process tests under load (`packages/eval` lifecycle cancellation, Runtime PTY ordering/rendering, and three existing `maka-cu` process timeout cases). The affected `@maka/computer-use` suite passed when rerun independently.
