CCO Patterns — share what the project has learned

Patterns are learned per-machine, per-project: which files are usually waste, which are usually useful, which get edited together. A teammate's fresh clone starts blind and re-learns the same lessons by wasting the same tokens.

This makes them portable. Run from the plugin root (the directory containing src/patterns-share.js).

Parse $ARGUMENTS:

export

node src/patterns-share.js export

Writes .cco/patterns.digest.json in the project (override with --out).
