HERE is now defined in boot.fth as `: HERE 12 @ ;` (reads SYSVAR_HERE
from WASM linear memory). The Rust side syncs user_here to memory[12]:
- At the start of each evaluate() call (sync_here_to_wasm)
- In each host function that modifies HERE (ALLOT, comma, C-comma, ALIGN)
This avoids per-token sync overhead — only 2 sync points per evaluate()
call plus host-function writes. Removed the HERE host function closure
(~30 lines). All 426 tests pass.
