feat(deploy): one physical line per command + post-deploy tests block

Every checklist command is emitted on exactly one line, however long; a
legacy backslash continuation in the runbook is joined at instantiation,
and bootstrap / learn patches write runbook lines the same way. After the
checklist the hand-back carries a Post-deploy tests block derived from the
delta diff: by-hand checks tied to delta files plus Suggestions for gaps.
Cold-resume re-display and re-hand-back regenerate both.

RED/GREEN on a scratch runbook: 4/4 baseline runs reproduced the
continuation verbatim and printed no tests; 4/4 runs on the edited skill
joined it and printed the block in the recipe's shape.
