fix: discover repository-local .agents skills in Settings

Skills listing ignored the active project when the OpenCode client
directory was unset, so project `.agents/skills` files were created but
never shown. Prefer the active project path (matching Commands/Agents)
and soft-fall back to it on skill API routes when directory is omitted.
