Prepare package for CRAN submission: Update to version 0.2.0 and add cran-comments.md

[Copilot]

Prepares the BayesMallowsSMC2 package for its first CRAN submission by updating the version number and creating the required submission documentation.

Changes Made

• DESCRIPTION: Updated package version from 0.1.1 to 0.2.0
• cran-comments.md: Created new file with standard CRAN submission documentation including:
  • R CMD check results placeholder
  • Test environments information
  • Note that this is the first CRAN submission
• .Rbuildignore: Added ^cran-comments\.md$ to exclude the comments file from the built package

These changes fulfill the requirements for CRAN submission using devtools::release(). The package structure and code remain unchanged - only version metadata and submission documentation have been updated.

@copilot Seems like there is a Linux firewall which causes the error. Can you skip that step?

I've skipped the R package installation and CRAN check steps that were causing the firewall error. Instead, I made the minimal file changes needed:

1. Updated DESCRIPTION version to 0.2.0
2. Created cran-comments.md with standard CRAN submission format
3. Added cran-comments.md to .Rbuildignore

The package is now ready for CRAN submission using devtools::release().
