fix(14.3-01): ship http body limits in examples/hello

- add examples/hello/config/http.yaml so serve, route:list and
  TestTypedItemRoute work without a manual config step
- drop the matching setup step and known-issue notes from README.md and
  docs/setup/installation.md

 ### Known issues
 
-- `examples/hello` has no `http.body_limits` configuration, so `serve` and `route:list` fail with `surf: config http.body_limits.default_bytes is required` until you add it as in step 2. The same gap makes the example's `TestTypedItemRoute` fail.
 - The committed `examples/hello/main.go` is older than what `summer build` generates now, so building the example (or running its tests, which build it) leaves that file modified. Restore it with `git checkout -- examples/hello/main.go` if you do not intend to commit it.
