/**

|
* resolveServerConfig PORT parsing tests: both the default (missing) and empty string
|
|
* (the common `PORT=` empty value in `.env`) fall back to 7364 — Number("") === 0 used
|
|
* to make the empty string pass range validation and bind to a random port; explicit
|
|
* "0" is preserved (explicit semantics for a random available port); invalid values
|
|
* throw. This matches the CLI's resolvePort semantics (packages/cli serve).
