The header value is a json object that contains the mountpoints of `fastn.app`s
If in FASTN.ftd, we have:
```ftd
-- import: fastn
-- fastn.package: hello-world
-- fastn.app: Auth App
package: lets-auth.fifthtry.site
mount-point: /-/auth/
-- fastn.app: Let's Talk App
package: lets-talk.fifthtry.site
mount-point: /talk/
```
Then the value will be a json string:
```json
{ "lets-auth": "/-/auth/", "lets-talk": "/talk/" }
```
NOTE: `lets-auth.fifthtry.site` and `lets-talk.fifthtry.site` are required to be a system
package. The names `lets-auth` and `lets-talk` are taken from their `system` field
