A JavaScript/TypeScript file with any parse diagnostic (a redeclaration,
a recoverable syntax error) was handed to the word-split fallback
tokenizer. Its tokens then never matched an oxc-tokenized file, so every
cross-file clone involving it vanished while its self-clones survived —
the symptom reported in #1023, where a second copy of a function in one
file made all a↔b clones disappear.
Tokens come from the lexer, not the parser: only `panicked` (or an empty
token stream) now triggers the fallback. Function extraction for
--similarity uses the partial AST on recoverable errors the same way.
Closes#1023.
