/**
 * Parse a string in the New Hampshire (Newick) format and return a tree object.
 *
 * This function reads a Newick string from left to right. It is based on
 * the `kn_parse` function by Heng Li for jstreeview (https://github.com/lh3/jstreeview/blob/main/knhx.js),
 * modified for compatibility with our Tree object and to prevent ';' assignment as root label.
 *
 * Supports node annotations in both BEAST [&...] and NHX [&&NHX:...] formats through the annotationParser parameter.
 * Users can provide their own annotation parser function to handle custom formats.
 * Also handles hybrid nodes marked with # notation following Cardona et al. 2008.
 *
 * If the input string contains multiple trees (separated by newlines), only the first tree is parsed
 * and a warning is issued. Use readTreesFromNewick() to parse multiple trees.
 *
 * Node IDs are unique and allocated in order of parsing. Specifically, leaf node IDs are numbered
 * according to the order in which they are encountered. Where a close parenthesis ')' is
 * encountered, an internal node is added with an incremented ID. This means that leaf node IDs
 * are not guaranteed to be contiguous or numbered from 0 to n-1. For example, for `(A,B);`, leaf A has index 1,
 * leaf B has index 2, and the root node has index 3. In general the root will have the highest index.
 *
 * To renumber nodes, one could use `.preorderTraversal()` or `.postorderTraversal()` methods.
 *
 * @param {string} newick - The string in Newick format to parse
 * @returns {Tree} - The constructed phylogenetic tree
