Represents a structural path to a property within an object.
A property path may be expressed as either a dotted string or a readonly array of exact PropertyKey
segments. Dotted strings provide concise access to ordinary string-keyed properties, while array paths preserve
strings, numbers, and symbols without coercion or delimiter ambiguity.
Exact array paths are required for numeric array indexes, symbol keys, empty-string keys, and property names
containing literal periods. Runtime APIs validate that paths are non-empty and may apply additional traversal or
mutation constraints.
