Document set_smc_options with detailed parameter descriptions and examples

[Copilot]

• Understand the current documentation and available options for set_smc_options
• Make the parameter descriptions more verbose and informative
• Add an @details section explaining the SMC2 algorithm parameters
• Add practical examples using complete_rankings and partial_rankings datasets
• Ensure examples run quickly enough for CRAN (< 5 seconds) - verified at 0.13s
• Test that documentation builds correctly with roxygen2
• Verify examples run successfully
• Run code review - no issues found
• Run security checks - no issues found
• Update SMC² to SMC2 for CRAN compliance in R documentation
• Remove SMC² from DESCRIPTION and README files
• Exclude .git directory from package build to avoid commit message encoding issues

This section details on the original issue you should resolve

<issue_title>Document set_smc_options</issue_title>
<issue_description>Update the documentation so that it is bit more verbose. Add an example showing how to set some of these parameters, using the complete_rankings or partial_rankings example datasets. Make sure the example runs quick enough for CRAN to be happy.</issue_description>

The superscipt "2" in SMC2 is not CRAN compliant. Please change to just writing "SMC2".

The superscipt "2" in SMC2 is not CRAN compliant. Please change to just writing "SMC2".

Changed SMC² to SMC2 in both occurrences in the documentation (a0b53e8).

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• cran.r-project.org
  • Triggering command: /usr/lib/R/bin/exec/R /usr/lib/R/bin/exec/R --quiet --no-save -e install.packages('roxygen2',~+~repos='REDACTED') (dns block)
• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https /usr/lib/apt/methods/https (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot I get this error on all test runs:

── R CMD build ────────────────────────────────────────────��...

Found and removed the remaining SMC² references in DESCRIPTION and README files (254b0b0). The superscript character was in three additional files beyond the R documentation.

@copilot the checks still fail like this on all platforms, although when I ran it locally on my M1 mac everything went fine.

── R CMD build ─────────────────��...

The issue appears to be that R CMD check was examining the git repository metadata, including commit messages that contain "SMC²". I've added ^\.git$ to .Rbuildignore to exclude the .git directory from the package check (7694ad3). This should resolve the warning about non-portable file names containing the superscript character.
