DOCA upgrade

Examples

• "Should I move to the next DOCA release?" — detect what is installed, report the gap, then STOP and ask. Never auto-upgrade.
• "apt upgrade drifted my DOCA packages." — this is recovery, not a silent repair. Detect, report, ask, then guide.

Quick answers (answer from this file)

• Not changing versions (a runtime error on the current, pinned install)? This skill does not apply: name doca-debug and stop.
