OpenCode's argument token is $ARGUMENTS, not $ARGUMENTS$. With the
extra dollar sign, OpenCode did not substitute the token, so the LLM
ended up writing the literal $ARGUMENTS$ line into the memory file
when no arguments were passed.
Adds a custom OpenCode command that scaffolds the compaction memory
file with ## Keep and ## Discard sections of classification rules.
The configured memoryFile path is substituted into both the command
description and the prompt template, and any arguments passed after
the command name are appended as user instructions.
