docs: fix incorrect code examples in guides

[productdevbook]

Summary

Fix 6 incorrect code examples across the documentation that would cause errors for users copying them:

File	Fix
docs/guide/basics/response.md	html(event, "...") → html("...") — html() doesn't take event arg
docs/guide/basics/error.md	onError(event, (event, error)) → onError((error, event)) — wrong signature and param order
docs/guide/basics/middleware.md	body → response.status — body was undefined variable
docs/guide/basics/handler.md	Remove stray ) — syntax error
docs/utils/response.md	for (let i = 0; i < 1000) → for (let i = 0; i < 1000; i++) — missing increment
src/utils/response.ts (JSDoc)	Same for loop fix in iterable() JSDoc
docs/guide/api/h3.md	event.path → event.url.pathname — deprecated property

Test plan

• Documentation only + 1 JSDoc fix
• No runtime code changes

Walkthrough

Docs and examples updated: middleware and hook examples adjusted, handler/response samples fixed for syntax and parameter usage, and iterable response example corrected with a loop increment and minor formatting fixes.

Changes

Cohort / File(s)	Summary
Middleware & Hooks docs/1.guide/1.basics/3.middleware.md, docs/1.guide/1.basics/6.error.md, docs/1.guide/900.api/1.h3.md	Adjusted example logging and callback signatures: onResponse example now logs response.status instead of body; onError example callback parameter order changed to (error, event); h3 hook example logs event.url.pathname instead of event.path.
Handler & Response examples docs/1.guide/1.basics/4.handler.md, docs/1.guide/1.basics/5.response.md	Fixed stray parenthesis, standardized wrapper parameter parentheses, added missing semicolon, and simplified html helper example to omit the event argument in the shortcut form.
Iterable / Response utility docs docs/2.utils/2.response.md, src/utils/response.ts	Corrected example generator loop to for (let i = 0; i < 1000; i++), adjusted generator/Promise formatting and closing punctuation in examples; no runtime API changes.

Poem

🐰 I hopped through docs with nibbling paws,
Fixed loops and commas, tweaked callback laws,
A status logged, a pathname found,
Small changes tidy the developer ground ✨
