Render a template by substituting `{{key}}` placeholders with values from a map. Missing keys are left as-is.
```sema
(prompt/render "Hello {{name}}, welcome to {{place}}."
{:name "Alice" :place "Wonderland"})
; => "Hello Alice, welcome to Wonderland."
(prompt/render "Hello {{name}}, {{missing}}." {:name "Bob"})
; => "Hello Bob, {{missing}}."
;; Non-string values are stringified
(prompt/render "Count: {{n}}" {:n 42})
; => "Count: 42"
```
