Capstone: core (internal)
This folder is the capstone suite's shared brain: references/
(core rules, protocols, craft files) and scripts/ (help, config
initializer, lint, and map-check.sh, the script half of map check
that the CI gate runs). Every other capstone skill resolves it as
../core/ from its own base directory, so install the whole suite;
a lone capstone skill without core cannot run.
Invoked directly, print the usage: run scripts/help.sh via bash
from this skill's base directory and output its stdout verbatim;
nothing else.
