Reduce cyclomatic complexity in lexer, parser, and program

Extract lookup tables for escape sequences (charTypeEscapes,
anchorEscapes, simpleEscapes), POSIX classes (posixClasses), and
opcode names (opNames) to replace large switch statements.

lexEscape: 49 → 22, instString: 33 → 10, posixClassRanges: 15 → 2.
Remaining high-complexity functions are dispatch switches inherent
to the VM/parser/compiler architecture.
