Documents the self-hosting process for js.sx including the G0 bug
where Python's `if fn_expr` treated 0/False/"" as falsy, emitting
NIL instead of the correct value. Adds live verification page,
translation differences table, and nav entry.

SX-to-JavaScript translator written in SX itself. When executed by the
Python evaluator against the spec files, produces output identical to
the hand-written bootstrap_js.py JSEmitter.
- 1,382 lines, 61 defines
- 431/431 defines match across all 22 spec files (G0 == G1)
- 267 defines in the standard compilation, 151,763 bytes identical
- camelCase mangling, var declarations, function(){} syntax
- Self-tail-recursive optimization (zero-arg → while loops)
- JS-native statement patterns: d[k]=v, arr.push(x), f.name=x
