Improve a Playbook

Turn Records, Suggestions, and new Versions into a learning loop.

Preserve the outcome and problem in the Case.
If the problem will recur, create a Suggestion against its base Version.
Review the Suggestion against the current Definition.
Publish a corrected immutable Version.
Resolve the Suggestion as applied with the result Version ID.

epismo suggestion create --playbook-id <playbook-id> \
  --base-version-id <version-id> \
  --title "Clarify review evidence" \
  --content "Add required evidence and acceptance criteria to Step ABCD"
epismo playbook version publish <playbook-id> \
  --base-version-id <latest-version-id> --input @revised.json
epismo suggestion resolve <suggestion-id> \
  --status applied --result-version-id <new-version-id>

Do not generalize every one-off exception, and do not apply an old-base Suggestion to latest without re-evaluating it.
