fix(lint/noOctalEscape): preserve string value when fixing octal escapes with leading digit 4-7 The Safe autofix computed the octal escape length by greedily consuming up to 5 following octal digits, ignoring ECMAScript Annex B.1.2: a legacy octal escape is at most 3 octal digits, and at most 2 when the leading digit is 4-7 (there is no `FourToSeven OctalDigit OctalDigit` production; max value is \377 = 255). Because action() slices text[index+1..index+len] and parses it as one octal number, `biome check --write` silently changed the runtime value of some string literals. For example "\751", which JS parses as "\75" (=) followed by the literal '1', was rewritten to the single character ǩ (U+01E9) instead of "\x3d1". Cap the number of trailing octal digits by the leading digit so the fix slices exactly what JavaScript parses. The diagnostic range shrinks automatically because diagnostic() and action() share RuleState.len. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
