Summary

Fixed PostgreSQL string escaping and made character offsets consistent across Go, JavaScript, and Python implementations.

Full changelog

Consistent character offsets for non-ASCII input. The parser now scans input by Unicode code point in all three languages (Go scans as []rune, JavaScript as Array.from(text)), so Range offsets advance one step per character regardless of byte or UTF-16 width. Previously Cyrillic and other multi-byte/astral characters desynced offsets across the Go, JavaScript, and Python ports.
Code-point token offsets in tokenize(). tokenize() now reports start/end as Unicode code-point offsets in every language, identical across Python, Go, and JavaScript for all input. Previously Go emitted byte-width token spans and JavaScript emitted UTF-16-code-unit spans for non-ASCII (and astral) characters, breaking the gap-free offset invariant.
Valid PostgreSQL string escaping. The PostgreSQL generator now emits escape-string literals (E'...') for values that contain backslash escapes such as quotes or newlines. A plain '...' literal treats backslashes literally under standard_conforming_strings (the default), which could produce invalid SQL; values that need no escaping still render as plain '...'.
