docs(readme): extended example has broken YAML indentation (server_dir appears as top-level key)

gh issue create --title "docs(readme): extended example has broken YAML indentation (server_dir appears as top-level key)" --label "documentation,audit,priority:medium" --body "## Finding

README.md's extended example section has a YAML block where server_dir (or another key) is mis-indented; it appears as a top-level key instead of under with:. The example is what most users copy-paste; broken indentation silently breaks their workflow.

## Affected code

- README.md — extended example

## Reproduction

1. Read README.md; inspect the extended example.

## Suggested fix

Re-indent the YAML block so all input keys are under `with:`. Validate with `yamllint` or a YAML-aware linter.

Open README.md and inspect the extended example's YAML block, focusing on the server_dir entry and the with: section. Run yamllint or another YAML-aware linter against the example. Done means all input keys are nested under with: and the example validates without indentation errors.
