Module exit 

Process exit codes.

Codes are part of the public contract: scripts and agents branch on them. Note what is deliberately not encoded here — “the result set was truncated” and “the result set was empty” are both success. Pagination state travels in the output text (see docs/adr/0003-output-ladder.md), never in the exit code.
