npm run bench (happy-dom, all three engines) and npm run bench:browser
(Playwright Chromium, the two ESM engines). Honest numbers recorded in
docs/v8.md: we create ~12% faster than µhtml in real Chromium (the
parse-once/clone design), µhtml updates in place ~5x faster than
fresh-tree + nanomorph (choo's architectural cost, mitigated by component
caching), and server strings are on par with nanohtml v1.

Three end-to-end scenarios against a static+SSR test server: the
zero-build page (import map + native ESM, no bundler), the SSR page
(rendered content in the raw response, live after hydration, no mismatch
warnings), and adoption (an expando on the server-rendered node survives
a real render). Renders are raf-batched so assertions poll.
Real Chromium flushed out three fixes happy-dom couldn't see:
- nanoraf called an extracted requestAnimationFrame bare — Illegal
invocation under strict-mode ESM (sloppy CJS had masked it); wrapped.
- the counter example only routed '/', so serving it from any subpath
threw; it now has a wildcard fallback.
- hydration mismatch detection is now whitespace-insensitive (the parser
reparents whitespace, e.g. text after </body>), and page scripts belong
in <head> when a view owns <body> — same convention bankai v9 used.
CI gets an e2e job with chromium-headless-shell.

Each template literal parses once, keyed by its strings array in a
WeakMap: static parts become a <template> with hole markers, renders
clone and fill. Interpolated values never pass through innerHTML (child
values become text nodes or adopted DOM; attributes go through
setAttribute). Event handlers set as properties so nanomorph copies them.
Document-level roots (<body>/<head>/<html>) parse via DOMParser because
<template> drops them. Replaces the v7 browserify transform entirely —
production speed is now a runtime property.
Tests run in happy-dom (new devDependency), including a check that server
and browser renderers serialize identical markup.

As described by #563:
> https://polyfill.io provides a fallback for browsers that don't support it, so for most people this will be a strict improvement.
`discify` is a different module than intended. discify is an alternative
to disc that works as a plugin, but we were using it as a separate
command line program. This switches it out for disc. The disc command
line program is called `discify` which is probably where the confusion
came from.
Also swapped out unassertify and uglifyify for tinyify, which adds tree
shaking.
