Grammar dialect widened to hold the battle-tested patterns verbatim
The ALR/engine citation grammars use fixed-width lookbehind
((?<![\w.]), (?<=[.!?])) and rf-string composition throughout, so a
dialect that bans lookbehind cannot take them without semantic
rewrites - exactly what must not happen. Lookbehind is now allowed
and the dual-runtime vector check is the gate: Python re only
compiles fixed-width, and a test proves a variable-width table fails
the round-trip while JS alone would have taken it. Tables gain defs
({{name}} fragments, fixpoint splicing, cycle-guarded, mirrored
byte-for-byte in the Python loader). The non-ASCII \uXXXX ban is
dropped - its premise measured false (Python re reads \uXXXX in
patterns); only JS-only \u{...} stays banned.
