Subject: [PATCH] feat: cover pi and opencode in the home-manager module

They have no @file imports, so the module concatenates the shared
claude-md fragments into one AGENTS.md per tool (.pi/agent/ and
.config/opencode/), and links commands/ into opencode's commands dir.
Skills need nothing: pi reads ~/.agents/skills and opencode auto-loads
both skill roots, all already linked.
