OpenCode's command route accepts file parts only. The server queue was
attaching captured context as text parts to POST /session/:id/command, so
a slash command queued with a comment, quote, or PR diff was rejected with
400 and retried forever.
A command queued without context still takes the command route with its
files. One queued with context now takes the prompt route the way the
composer does: the command's template is expanded with its arguments, a
skill keeps its text and gets the explicit skill-invocation instruction,
and the context rides along.
