Standardize archive command documentation to use `<change-id>` instead of `[change]` to clarify that the change ID must be explicitly passed. Remove OpenCode-specific slash command reference from AGENTS.md to keep it tool-agnostic.
* feat: add argument support to archive slash command
Add $ARGUMENTS placeholder to the /openspec:archive slash command to allow explicit change ID specification, improving safety and matching CLI behavior.
Changes:
- Add $ARGUMENTS to archive command frontmatter in OpenCode configurator
- Update archive command template with argument validation steps
- Add rewriteArchiveFile method to handle managed section updates
- Update AGENTS.md documentation for archive command usage
This change makes it possible for users to run `/openspec:archive <change-id>` instead of relying on context inference, reducing the risk of archiving the wrong change.
* refactor: improve archive slash command argument handling instructions
Update the archive slash command template to provide clearer guidance on how
to handle change IDs from arguments versus conversation context. The new
instructions better distinguish between explicit argument-provided IDs and
contextual references, and provide more explicit failure modes.
