Adds Go's concurrency + iteration primitives to the statement parser:
go EXPR → (list :go EXPR)
defer EXPR → (list :defer EXPR)
ch <- v → (list :send CHAN VALUE)
for range COLL { ... } → (list :range-for nil nil nil COLL BODY)
for k := range C { ... } → (list :range-for :short-decl KEY nil COLL BODY)
for k, v := range C { } → (list :range-for :short-decl KEY VAL COLL BODY)
for k, v = range C { ... } → (list :range-for :assign KEY VAL COLL BODY)
gp-for-find-range pre-scans the for-header (to '{' or eof) looking
for the 'range' keyword; if present, dispatches to gp-parse-for-range
which handles the four range shapes. C-style and while-like and
infinite are now in gp-parse-for-c-style — gp-parse-for is just a
dispatcher.
Send statement detection lives in the LHS-list branch of gp-parse-stmt:
after parsing a single LHS expression, '<-' triggers (:send LHS RHS).
Channel-recv (`<-ch`) was already parsed as unary `<-` in the expression
layer, so both directions cover.
This is the **chiselling-relevant iteration** for the scheduler sister
kit: the AST shapes Go-on-SX will eventually feed into the kit's
scheduler primitives (sched-spawn, sched-defer, chan-op) have landed.
Sister-plan diary updated with three design insights:
* :go / :defer both wrap a single expr — kit's sched-spawn should
accept a thunk uniformly across Erlang's spawn(M,F,A) and Go's
go fn().
* :send carries CHAN+VALUE symmetrically with the unary <- recv —
both reduce to (chan-op direction chan value) in the kit.
* `for v := range ch` uses the same :range-for shape as range-over-
slice; the scheduler kit's range dispatch is where chan-recv ⇄
iteration polymorphism lives.
parse 161/161, total 290/290.
