06666ac8c4 Decouple core evaluator from web platform, extract libraries 
The core evaluator (spec/evaluator.sx) is now the irreducible computational
core with zero web, rendering, or type-system knowledge. 2531 → 2313 lines.

- Add extensible special form registry (*custom-special-forms* + register-special-form!)
- Add render dispatch hooks (*render-check* / *render-fn*) replacing hardcoded render-active?/is-render-expr?/render-expr
- Extract freeze scopes → spec/freeze.sx (library, not core)
- Extract content addressing → spec/content.sx (library, not core)
- Move sf-deftype/sf-defeffect → spec/types.sx (self-registering)
- Move sf-defstyle → web/forms.sx (self-registering with all web forms)
- Move web tests (defpage, streaming) → web/tests/test-forms.sx
- Add is-else-clause? helper (replaces 5 inline patterns)
- Make escape-html/escape-attr library functions in render.sx (pure SX, not platform-provided)
- Add foundations plan: Step 3.5 (data representations), Step 3.7 (verified components), OCaml for Step 4d
- Update all three bootstrappers (JS 957/957, Python 744/744, OCaml 952/952)

e475222099 Merge eval.sx + frames.sx + cek.sx into single evaluator.sx 
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.

72eaefac13 Phase 4: Move web framework files to web/ and web/tests/ 
signals.sx, engine.sx, orchestration.sx, boot.sx, router.sx, deps.sx,
forms.sx, page-helpers.sx, adapters, boundary files → web/
Web tests → web/tests/
Test runners updated with _SPEC_TESTS and _WEB_TESTS paths.
All 89 tests pass (20 signal + 43 CEK + 26 CEK reactive).
Both bootstrappers build fully (5993 Python lines, 387KB JS).

7036621be8 Phase 3: Move host files to hosts/python/ and hosts/javascript/ 
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/.
