HS parser: fix number+comparison keyword collision, eval-hs uses hs-compile

Parser: skip unit suffix when next ident is a comparison keyword
(starts, ends, contains, matches, is, does, in, precedes, follows).
Fixes "123 starts with '12'" returning "123starts" instead of true.

eval-hs: use hs-compile directly instead of hs-to-sx-from-source with
"return " prefix, which was causing the parser to consume the comparison
as a string suffix.
