Replace two-part positive integer check (^[0-9]+$ + -eq 0) with single regex ^[1-9][0-9]*$ that inherently rejects zero and non-numeric input. Addresses PR #4062 review feedback for defense-in-depth consistency.

Code Review
This pull request refactors the validation for the --interval argument in cron.sh. The previous two-step validation, which used a regex and an arithmetic comparison, is replaced by a single regex ^[1-9][0-9]*$. This change enforces that the interval is a positive integer and disallows leading zeros. The review of this change did not identify any issues.

Summary
--intervalvalidation (^[0-9]+$+-eq 0check) with single regex^[1-9][0-9]*$for defense-in-depth against injection when parsing numeric data from untrusted sources--concurrencyvalidation pattern in the same codebaseDetails
File:
.agents/scripts/supervisor-archived/cron.sh:38-42Before:
if ! [[ "$2" =~ ^[0-9]+$ ]] || [[ "$2" -eq 0 ]]; thenAfter:
if ! [[ "$2" =~ ^[1-9][0-9]*$ ]]; thenThe single regex rejects
0,00,007-style inputs, and non-numeric strings in one check. The-eq 0arithmetic comparison is no longer needed, which also avoids potential issues if the value somehow bypasses the first regex check.Closes #4078
