v0.6.8 feat: codify pull-request descriptions

[indykish]

Session notes 1

PR and MR descriptions now append one numbered unit with pictorial notes,
review dispositions, and command evidence. Both forge paths share the rule;
no work is deferred.

   BEFORE                                AFTER
   ┌───────────────────────────┐         ┌───────────────────────────┐
   │ 18 dispatch entries       │         │ 19 dispatch entries       │
   │ no PR/MR body shape       │         │ 29 audit scenarios        │
   └───────────────────────────┘         │ 36,002 / 37,888 bytes     │
                                         └───────────────────────────┘
