Therapy.jl-powered docs site with live playground

Replace Documenter.jl docs with Therapy.jl-powered site:
- Same framework as Therapy.jl docs, Julia Purple accent color
- Routes: homepage (with embedded playground iframe), getting-started, API
- Layout: JST wordmark, nav, footer, same warm palette
- Live playground embedded via iframe on homepage
- Old Documenter.jl docs archived to docs-old/

Docs structure:
- docs/app.jl — Therapy.jl App config
- docs/input.css — Tailwind v4 with purple accent
- docs/src/components/Layout.jl — Site layout
- docs/src/routes/ — File-based routing
- docs/src/playground/ — Self-hosted browser compiler (parser+lowerer+infer+codegen)

CI: GitHub Actions builds via julia --project=docs docs/app.jl build,
copies playground to dist, deploys to GitHub Pages.

JST compilation improvements (25+ operations):
- sort, filter, map, copy, reverse, setindex!, deleteat!, in
- lowercase, uppercase, contains, startswith, endswith, split, join, strip
- zeros, ones, fill, parse, reduce, any, all, findfirst
- :sgt_int, :sge_int intrinsics
- Handlers in both compile_invoke AND compile_call (optimized + unoptimized IR)
- contains arg order fix: contains(haystack, needle)

Tests: 13 e2e tests via Node.js — actual output comparison
