- Implement check-billing.sh script that verifies the most recent
transcript has entrypoint 'cli' (subscription pool) not 'sdk-cli'
- Script finds newest *.jsonl under ~/.claude/projects/ and scans
for entrypoint field, exiting 0 iff it equals 'cli'
- Handle no-transcripts and no-directory cases with distinct errors
- Update README with Troubleshooting and Release checklist sections
referencing the script as the pre-release gate
Acceptance criteria:
- bash -n passes (syntax valid)
- Executable mode 755
- README updated with troubleshooting/release checklist references

The watchdog mechanism was complete but had an inconsistency:
main.rs used exit code 3 for timeout errors while ClaudePrintError::Timeout.exit_code()
returned 124 (GNU timeout convention). Now uses the proper exit code from the error type.
This ensures timeout errors exit with the standard code 124, matching GNU timeout
behavior and making error handling consistent for callers (marathon loop/NEEDLE).
