chore(scripts): make prepare script ignore symlink creation failures

Add "|| true" to the ln -s command in the prepare script to prevent
the entire prepare process from failing when symlink creation doesn't
work. This ensures that git hooks setup and schema generation can
complete successfully even in environments where symlink creation
fails (such as certain Windows configurations or restricted
filesystems).

The symlink from CLAUDE.md to AGENTS.md is helpful for development
but not critical for the package to function properly.
