fix(exec): treat shell exit codes 126/127 as failures instead of completed

Browse Source 
When a command exits with code 127 (command not found) or 126 (not
executable), the exec tool previously returned status "completed" with
the error buried in the output text. This caused cron jobs to report
status "ok" and never increment consecutiveErrors, silently swallowing
failures like `python: command not found` across multiple daily cycles.

Now these shell-reserved exit codes are classified as "failed", which
propagates through the cron pipeline to properly increment
consecutiveErrors and surface the issue for operator attention.

Fixes #24587
