chore: release v0.3.1

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.

 # Changelog
 
+## 0.3.1
+
+- Fix the OpenCode `$ARGUMENTS` token in the `plugin-compaction-init` template so it is properly substituted instead of being written into the memory file.
+
 ## 0.3.0
 
 - Auto-register a `/plugin-compaction-init` slash command that scaffolds the compaction memory file with `## Keep` and `## Discard` sections of classification rules. User-supplied arguments are appended to extend the defaults.
