giles 60bb77d365 js-on-sx: parseInt digit-walker, parseFloat prefix, Number('abc')→NaN, encodeURIComponent ...

Four coercion fixes that together unblock many test262 cases:

1. js-to-number(undefined) now returns NaN (was 0). Fixes Number(undefined),
   isNaN(undefined), Math ops on undefined.
2. js-string-to-number returns NaN for non-numeric strings (via new
   js-is-numeric-string?). Previously returned 0 for 'abc'.
3. parseInt('123abc', 10) → 123 (walks digits until first invalid char),
   supports radix 2..36.
4. parseFloat('3.14xyz') → 3.14 (walks float prefix).
5. encodeURIComponent / decodeURIComponent / encodeURI / decodeURI —
   new URI-helper implementations.

8 new unit tests, 514/516 total.
