28 tests, passes on both JS and OCaml.
- spec/stdlib.sx: pure SX format function
- spec/primitives.sx: format primitive declaration
- lib/r7rs.sx: fix number->string to support optional radix arg
- hosts/ocaml: add format-decimal primitive, load stdlib.sx in test runner
- hosts/javascript: load stdlib.sx in test runner

spec/ now contains only the language definition (5 files):
evaluator.sx, parser.sx, primitives.sx, render.sx, special-forms.sx
lib/ contains code written IN the language (8 files):
stdlib.sx, types.sx, freeze.sx, content.sx,
bytecode.sx, compiler.sx, vm.sx, callcc.sx
Test files follow source: spec/tests/ for core language tests,
lib/tests/ for library tests (continuations, freeze, types, vm).
Updated all consumers:
- JS/Python/OCaml bootstrappers: added lib/ to source search paths
- OCaml bridge: spec_dir for parser/render, lib_dir for compiler/freeze
- JS test runner: scans spec/tests/ (always) + lib/tests/ (--full)
- OCaml test runner: scans spec/tests/, lib tests via explicit request
- Docker dev mounts: added ./lib:/app/lib:ro
Tests: 1041 JS standard, 1322 JS full, 1101 OCaml — all pass

Three changes that together enable the full 46-function stdlib migration:
1. CEK callable unification (spec/evaluator.sx):
cek-call now routes both native callables and SX lambdas through
continue-with-call, so replacing a native function with an SX lambda
doesn't change shift/reset behavior.
2. Named-let transpiler support (hosts/javascript/transpiler.sx):
(let loop ((i 0)) body...) now transpiles to a named IIFE:
(function loop(i) { body })(0)
This was the cause of the 3 test regressions (produced [object Object]).
3. Full stdlib via runtime eval (hosts/javascript/bootstrap.py):
stdlib.sx is eval'd at runtime (not transpiled) so its defines go
into PRIMITIVES without shadowing module-scope variables that the
transpiled evaluator uses directly.
stdlib.sx now contains all 46 library functions:
Logic: not
Comparison: != <= >= eq? eqv? equal?
Predicates: boolean? number? string? list? dict? continuation?
zero? odd? even? empty?
Arithmetic: inc dec abs ceil round min max clamp
Collections: first last rest nth cons append reverse flatten
range chunk-every zip-pairs
Dict: vals has-key? assoc dissoc into
Strings: upcase downcase string-length substring string-contains?
starts-with? ends-with? split join replace contains?
Text: pluralize escape parse-datetime assert
All hosts: JS 957+1080, Python 744, OCaml 952 — zero regressions.

The irreducible primitive set drops from 79 to 33. Everything that can
be expressed in SX is now a library function in stdlib.sx, loaded after
evaluator.sx and before render.sx.
Moved to stdlib.sx (pure SX, no host dependency):
- Logic: not
- Comparison: != <= >= eq? eqv? equal?
- Predicates: nil? boolean? number? string? list? dict? continuation?
empty? odd? even? zero? contains?
- Arithmetic: inc dec abs ceil round min max clamp
- Collections: first last rest nth cons append reverse flatten range
chunk-every zip-pairs vals has-key? merge assoc dissoc into
- Strings: upcase downcase string-length substring string-contains?
starts-with? ends-with? split join replace
- Text: pluralize escape assert parse-datetime
Remaining irreducible primitives (33):
+ - * / mod floor pow sqrt = < > type-of symbol-name keyword-name
str slice index-of upper lower trim char-from-code list dict concat
get len keys dict-set! append! random-int json-encode format-date
parse-int format-decimal strip-tags sx-parse error apply
All hosts: JS 957+1080, Python 744, OCaml 952 — zero regressions.
