Validate deployment health across targets

Audit deployment configs via read-only verification passes

Validating deployment configuration correctness and health before release without risking mutation of running systems.

• · optional: array of target names (images/deploys) to audit
• · charly.yml / box.yml / deploy.yml config files

• · validation report (ok, warnings, errors)
• · per-target health verdict (healthy | DEGRADED | NOT-RUNNING | CHECKS-FAILED | NOT-BUILT)
• · failing checks list with verbatim output

• · charly CLI (box validate, eval box, eval live, status)
• · bash shell

• · charly CLI installed and in PATH
• · box.yml / charly.yml files present
• · Built images exist locally if auditing built status
• · Current deploy accessible if auditing live status

• · charly box validate returns errors → blocks audit (no fallback)
• · Built image not found locally → target marked NOT-BUILT (non-fatal)
• · Deploy not currently running → target marked NOT-RUNNING (non-fatal)
• · Health probe timeout → skipped (non-fatal)

• · Read-only design: never builds, deploys, rebuilds, or tears down
• · Three independent probe types (box validate, box eval, live eval)
• · Verbatim failing check output surfaced (never hidden)
• · Schema validation enforces all returned fields (ok, warnings, errors, health verdict)
