refactor(lang): rename builtins flr->floor and fx->fixed

Browse source 
De-abbreviate the two bare fixed-point conversion builtins:
  flr(f) -> int     ->  floor(f) -> int    (fixed -> int, flooring)
  fx(i)  -> fixed   ->  fixed(i) -> fixed  (int -> fixed; mirrors how the
                                            stringify builtin is `string`)

Updates the compiler dispatch, all call sites, the grammars/LSP/JetBrains
tokens, and the docs (fn-flr -> fn-floor, fn-fx -> fn-fixed). Reseeded;
C-free fixpoint holds; all suites green (45/24/29); site + check.py OK.

# The EV2 reflection ABI (the world table), exposed to Ludic so a Ludic mod can
# introspect the world by name — the same functions a foreign mod binds. Emitted
# only for a modding program (ECS + events), so a plain game is unchanged.
