The server tag now builds a parts list (string runs + async holes) instead
of an eager string. Sync templates collapse to one string and toString()
is byte-identical to before. Promises and async iterables in child
position make the result streamable: iterating it yields everything before
a hole immediately, then each hole as it resolves, in document order —
resolved values get full child semantics (templates, arrays, raw,
escaping). toString() on async content throws with streaming guidance;
async values in attribute position throw immediately.

hydrate(oldNode, newNode) normalizes the client tree to parser text-node
granularity, walks both trees to report the first server/client markup
disagreement (node, text, attribute, or child count, with a path), then
morphs — matching nodes are adopted in place, the client render wins.
choo.mount() now hydrates and console.warns on mismatch.
Building this surfaced two real isomorphism divergences, both fixed:
adjacent text nodes from template holes vs the parser's merged runs
(folded via Node.normalize), and the server serializing onclick="" where
the browser sets a property — event handlers now leave no trace in server
markup at all.

ESM ports with attribution: nanohtml 1.10.0 server tag (browserify/babel
transform branches removed — pure runtime), raw-server, and nanomorph 5.4.3
consolidated into one module. browser.js is a Phase 2 placeholder that
throws loudly. Covered by test/server.test.js on node:test.
