[Bug]: Sessions and Cron commands accept negative --limit values #1558

OpenSquilla version or commit

0.5.4

Area

CLI

Reproduction steps

With more than one session and at least one Cron run:

opensquilla sessions list --limit -1 --json
opensquilla cron runs <job-id-with-run-history> --limit -1 --json

Expected behavior

Reject values below 1 consistently at the CLI/RPC boundary with exit code 2 and, in JSON mode, a structured invalid-parameter error.

Actual behavior

Both commands exit 0 and return records. For sessions, -1 effectively removes or changes the intended limit rather than failing validation.

For comparison, Memory search rejects a negative limit with a structured params.limit must be >= 1 error.

Environment
