ocaml-linkedin: apply dune fmt
Pure formatting changes from `dune fmt`: doc comment placement moves
from above the binding to below it for `type`s, multi-line `match`
expressions collapse onto one line where they fit, and infix operator
applications pick up spaces (`Soup.($?)` -> `Soup.( $? )`). No
semantic changes.

## Example
32

33
+
Derive protocol-specific keys with HKDF or password-derived keys with
34
+
PBKDF2/scrypt, depending on the secret material you start with:
35
+
36
+
```ocaml
37
+
let salt = "deployment-2026"
38
+
let ikm = "shared input key material"
39
+
40
+
let key =
41
+
let prk = Hkdf.extract ~hash:`SHA256 ~salt ikm in
42
+
Hkdf.expand ~hash:`SHA256 ~prk ~info:"api-token" 32
