Function concatPropertyPath

concatPropertyPath(
path: PropertyPath,
...paths: PropertyPath[],
): readonly PropertyKey[]
Concatenates one or more property paths into a newly allocated exact property-key path.

Every path is normalized before concatenation. Dotted strings therefore contribute one segment per delimiter, while array property-keys preserve numbers, symbols, empty-string keys, and literal periods exactly. The returned array is independent of every input array and may be retained or modified by the caller without affecting those inputs.
Parameters
- path: PropertyPath
  First path to concatenate.
- ...paths: PropertyPath[]
  Additional property paths appended in order.
Returns readonly PropertyKey[]
A newly allocated exact property-key path.
Example
```
concatPropertyPath('actor.system', ['attributes', 'hp'], 'value');
// ['actor', 'system', 'attributes', 'hp', 'value']
```
Throws
If any argument is not a valid PropertyPath or no path is supplied at runtime.
