1// `supercode skills install`: the skills this release carries (skills/<name>/SKILL.md beside lib/), put into every

2// agent harness's skills folder in this OS user's home, and the messaging tools registered with each harness

4// by hand, so an agent on a machine (or under WSL) with none did not know supercode.

6// Idempotent. A skill folder this installs carries a marker (`.supercode-release`: the release that wrote it and a hash
