v1.2.1 — Fix OpenCode directory names

Bug Fix

OpenCode installer: singular directory names

OpenCode discovers agents in agent/ and skills in skill/ (singular), not agents/ or skills/ (plural). The v1.2.0 installer used plural names, so OpenCode silently ignored the installed files.

Fixed: Converter now installs to agent/, command/, skill/ — all singular, matching OpenCode's layout exactly.

command/ was already correct in v1.2.0.

Upgrade
