refactor(selfhost): reorganise into concern-based subdirectories
Split the flat 38-file selfhost/ into concern-based subdirectories:

  frontend/        lex, parse, parse_game, ast
  support/         str, buf, io
  backend/         core IR + expression/statement lowering
  backend/game/    ECS/scene/event/world lowering
  backend/stdlib/  the namespaced Math.*/Text.*/Crypto.*/… intrinsics

and split the three oversized emitters at responsibility boundaries so
no file mixes concerns:

  emit_game.ludic  -> + emit_world.ludic         (reflection world table,
                                                  tick helpers, @main synthesis)
  emit_expr.ludic  -> + emit_call.ludic          (namespaced builtins, call
                                                  lowering, expr dispatch)
  emit_text.ludic  -> + emit_text_prelude.ludic  (emitted string-builder runtime)

FRAGS in tools/x/selfhost.ludic is updated to the new paths with the link
order preserved, and the Python doc/vocabulary tooling is updated to walk
the new layout. Because the build is a plain in-order concatenation and
every split lands on a blank-line boundary, the regenerated seed is
byte-identical: `x reseed` leaves selfhost/ludicc.seed.ll unchanged,
`x bootstrap-cfree` still reaches its fixed point, and both `x test` (56)
and `x selfhost-test` (29, incl. golden renders) stay green.

Closes #29

# emit_time.ludic — the Time.* namespace. frame/elapsed/delta are deterministic

# the wall clock and is explicitly non-deterministic. The frame clock ticks at a
# fixed 60 per second, so delta is the constant 1/60 s = 1092 in Q16.16.
