Three parse-cmd / parse-feat refinements:
1. Remove dict-branch from arith guard: span-mode=true produces dict nodes
with :kind "arith", not lists. The guard only needs the list-branch (for
span-mode=false). Without this, hs-src "x + y" threw a parse error.
2. parse-feat top-level expression-first fallback: when no feature keyword is
found, try parse-expr first. If it fully consumes the input (at-end?),
return the expression directly — bypassing parse-cmd and its arith guard.
This matches upstream _hyperscript("1 + 1") which evaluates as an
expression, not a pseudo-command.
3. paren-close exception in arith guard: when the token after the arithmetic
expression is ")", we are inside a parenthesised context (e.g. "(0+1) em"
string-postfix). Allow it through without the pseudo-command error.
