* fix(captain): review pass 1: 'do it' parses as rec, READY template matches the tool's lines, slot-2 and freeze wording, mergeChangelogs named, parameter lists and doc numbers aligned

* fix(captain): align the slot-call BASE merge, freeze repair and severe-race wording across skill, CREW.md and docs; router routes on phrases; receipt head width as printed
