fix: standardize list command count fields and resume help field name

#410: Added  field to mcp list and skills list JSON for
polymorphic consumption parity with agents list. All three sibling
list commands now expose a canonical  integer field alongside
their command-specific details.

#338: Changed resume  JSON from  to  field for
consistency with top-level .
