dom-lib and browser-lib were listed in ADAPTER_FILES but never actually
transpiled — their functions only existed as native PLATFORM_*_JS code.
Add them to the build loop so the FFI library wrappers are compiled.
Add hostCall/hostGet/etc. variable aliases for transpiled code, and
console-log to browser.sx for runtime-eval'd SX code.

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.

The core spec is now one file: spec/evaluator.sx (2275 lines).
Three parts:
Part 1: CEK frames — state and continuation frame constructors
Part 2: Evaluation utilities — call, parse, define, macro, strict
Part 3: CEK machine — the sole evaluator
Deleted:
- spec/eval.sx (merged into evaluator.sx)
- spec/frames.sx (merged into evaluator.sx)
- spec/cek.sx (merged into evaluator.sx)
- spec/continuations.sx (dead — CEK handles shift/reset natively)
Updated bootstrappers (JS + Python) to load evaluator.sx as core.
Removed frames/cek from SPEC_MODULES (now part of core).
Bundle size: 392KB → 377KB standard, 418KB → 403KB full.
All tests unchanged: JS 747/747, Full 864/870, Python 679/679.

- Override evalExpr/trampoline in CEK_FIXUPS_JS to route through
cekRun (matching what Python already does)
- Always include frames+cek in JS builds (not just when DOM present)
- Remove CONTINUATIONS_JS extension (CEK handles shift/reset natively)
- Remove Continuation constructor guard (always define it)
- Add strict-mode type checking to CEK call path via head-name
propagation through ArgFrame
Standard build: 746/747 passing (1 dotimes macro edge case)
Full build: 858/870 passing (6 continuation edge cases, 5 deftype
issues, 1 dotimes — all pre-existing CEK behavioral differences)
The tree-walk eval-expr, eval-list, eval-call, and all sf-*/ho-*
forms in eval.sx are now dead code — never reached at runtime.

Python: bootstrap.py, platform.py, transpiler.sx, boundary_parser.py, tests/
JavaScript: bootstrap.py, cli.py, platform.py, transpiler.sx
Both bootstrappers verified — build from new locations, output to shared/.
