Max MedveandGitHub 3a0d80d1f4 perf(parser): memoize createTrie to avoid rebuilding tries per Tokenizer (#911) ...

The Tokenizer constructor calls createTrie(operators) and
createTrie(literalValues) on every instantiation, and liquidjs builds a
fresh Tokenizer per output/tag while parsing. On typical templates this
rebuilt the same prefix-tries dozens of times and showed up as a large
share of parse CPU in profiling.

Memoize createTrie with a module-level WeakMap keyed on the input object.
The inputs (operators, literalValues) are stable references and the trie
is only ever read afterward (via matchTrie), never mutated, so caching by
reference is behavior-preserving. WeakMap (not Map) lets short-lived,
per-instance operator objects and their tries be garbage collected.
