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 playbook suggestion create <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.
