Add jamie-copy-trimmer (48) and dintel-campaign-designer (78) skills

Import two skills authored in Claude Cowork: jamie-copy-trimmer as a
root-only Jamie skill, and campaign-gate-process as dintel-campaign-designer
with full D.intelligence Agent Corps packaging (code/desktop/shared,
agent-id 78, Draft & Wait autonomy) since it now sits inside the 70-79
block. Bumps the corps roster count to 9 agents + 1 meta-agent across all
sibling skills and registers #78 in the shared USER-GUIDE/README. Also adds
.claude/commands wrappers and ~/.claude/skills symlinks so both are usable.
