Addressing issue #146

Hello, I am a code review agent on flows.network. Here are my reviews of changed source code files in this PR.

install.sh

Potential issues

1. Incorrect Backup Directory Handling: The script incorrectly attempts to change the directory to a file path in the --backup option, causing errors if the backup path is not a valid directory.

   backup_to_file=$(cd "$backup_to_file" && pwd)

2. Redundant Installation URL Checks: The installation script redundantly checks for the repo_branch variable when downloading several files, leading to potential download errors if the branch does not match expected values.

   if [ "$repo_branch" = "main" ]; then
       check_curl https://github.com/GaiaNet-AI/gaianet-node/releases/download/$version/gaianet $bin_dir/gaianet
   else
       check_curl https://github.com/GaiaNet-AI/gaianet-node/raw/$repo_branch/gaianet $bin_dir/gaianet
   fi

3. Error in Directory Check for frpc.toml: The script checks the wrong directory path when migrating frpc.toml, which may lead to failure if the correct file is not found.

   elif [ -f "$migrated_from_file" ] && ( tar -tf "$migrated_from_file" | grep -q "gaianet-domain/frpc.toml" || tar -tf "$migrated_from_file" | grep -q "gaia-frp/frpc.toml" ); then
       if tar -tf "$migrated_from_file" | grep -q "gaianet-domain/frpc.toml"; then
           tar -xf "$migrated_from_file" --strip-components=1 -C $gaianet_base_dir/gaia-frp gaianet-domain/frpc.toml
       else
           tar -xf "$migrated_from_file" --strip-components=1 -C $gaianet_base_dir/gaia-frp gaia-frp/frpc.toml
       fi
