Include limit and bytes received in output_limit_exceeded errors

[shrisukhani]

Summary

output_limit_exceeded errors now report the configured maxOutputBytes and the number of bytes received. This brings the Node SDK in line with the matching python-sdk change.

Changes

• Message: Command output exceeds maxOutputBytes (8 bytes received, limit 4); increase the collection limit or disconnect a detached process
• details now also includes max_output_bytes and received_bytes, next to the existing process_id and last_seq.
• ProcessOutput.failure() takes an optional details record. The python_reference.json fixtures still pass because they match details as a subset.

Validation

• npm run lint, npm run typecheck
• vitest run tests/unit/process-collection.test.ts tests/unit/python-reference.test.ts (254 passed), including a new test for the error message and details

Note

Low Risk
Only enriches error messaging and metadata for an existing failure path; no change to collection logic or limits.

Overview
output_limit_exceeded errors now tell callers exactly how much output was collected versus the configured cap, matching the Python SDK behavior.

When command output exceeds maxOutputBytes, the error message includes received bytes and the limit, and HyperbrowserError.details adds max_output_bytes and received_bytes alongside the existing process_id and last_seq. ProcessOutput.failure() accepts an optional extra details map that is merged into those error details.

A unit test asserts the new message text and detail fields when exec hits the limit.
