Move to boot.fth: TYPE, SPACES, <#, HOLD, HOLDS, SIGN, #, #S, #>, ., U., .R, U.R, D., D.R. The Forth . now uses pictured numeric output (standard Forth approach) instead of a Rust formatting closure. Add M*, UM*, UM/MOD host functions to the WASM runner so that the Forth # word (which calls UM/MOD) works in standalone mode. Removed 660 lines of Rust closures + 5 dead helper functions. All 426 tests pass.
