Plugin-prefixed aliases are now excluded by default to avoid duplicate
completions. Use verbose mode (-v) to include all aliases.

* Filter only true duplicates.

Date does not have setTimezone() method, only DateTime does.
Add instanceof check to prevent calling setTimezone on Date objects.

This matches the pattern already used in dateAgoInWords().

The return type `array<string, array<string, string>>` was too restrictive
and didn't account for nested validators. When using `addNested()` or
`addNestedMany()`, the error values can be nested arrays, not just strings.

Updated the return type to `array<string, array<string, string|array>>`
which accurately reflects the actual return structure.

Fixes #19112

Fix return type annotation for Validator::validate()
