xj 86dc0feeb4 fix: prevent shell injection in opencode-agents workflow (#722)
The triage-issue job interpolated $ISSUE_TITLE and $ISSUE_BODY unquoted
inside a double-quoted shell string, allowing any GitHub user to execute
arbitrary commands by opening an issue with shell metacharacters.

The duplicate-prs job similarly interpolated $COMMENT unquoted into a
gh pr comment --body argument.

Fix both by using printf with %s (prevents shell interpretation) and
--body-file (avoids inline interpolation entirely).
