Restructure SX ref spec into core + selectable adapters

Split monolithic render.sx into core (tag registries, shared utils) plus
four adapter .sx files: adapter-html (server HTML strings), adapter-sx
(SX wire format), adapter-dom (browser DOM nodes), and engine (SxEngine
triggers, morphing, swaps). All adapters written in s-expressions with
platform interface declarations for JS bridge functions.

Bootstrap compiler now accepts --adapters flag to emit targeted builds:
  -a html        → server-only (1108 lines)
  -a dom,engine  → browser-only (1634 lines)
  -a html,sx     → server with SX wire (1169 lines)
  (default)      → all adapters (1800 lines)

Fixes: keyword arg i-counter desync in reduce across all adapters,
render-aware special forms (let/if/when/cond/map) in HTML adapter,
component children double-escaping, ~prefixed macro dispatch.

Update reference SX spec to match sx.js macros branch (CSSX, dict literals, new primitives)

- eval.sx: Add defstyle, defkeyframes, defhandler special forms; add ho-for-each
- parser.sx: Add dict {...} literal parsing and quasiquote/unquote sugar
- primitives.sx: Add parse-datetime, split-ids, css, merge-styles primitives
- render.sx: Add StyleValue handling, SVG filter elements, definition forms in render, fix render-to-html to handle HTML tags directly
- bootstrap_js.py: Add StyleValue type, buildKeyframes, isEvery platform helper, new primitives (format-date, parse-datetime, split-ids, css, merge-styles), dict/quasiquote parser, expose render functions as primitives
- sx-ref.js: Regenerated — 132/132 tests passing

Add bootstrap compiler: reference SX spec → JavaScript

bootstrap_js.py reads the reference .sx specification (eval.sx, render.sx)
and transpiles the defined evaluator functions into standalone JavaScript.
The output sx-ref.js is a fully functional SX evaluator bootstrapped from
the s-expression spec, comparable against the hand-written sx.js.

Key features:
- JSEmitter class transpiles SX AST → JS (fn→function, let→IIFE, cond→ternary, etc.)
- Platform interface (types, env ops, primitives) implemented as native JS
- Post-transpilation fixup wraps callLambda to handle both Lambda objects and primitives
- 93/93 tests passing: arithmetic, strings, control flow, closures, HO forms,
  components, macros, threading, dict ops, predicates

Fixed during development:
- Bool before int isinstance check (Python bool is subclass of int)
- SX NIL sentinel detection (not Python None)
- Cond style detection (determine Scheme vs Clojure once, not per-pair)
- Predicate null safety (x != null instead of x && to avoid 0-as-falsy in SX)
