fix(Select): clear input after pasting text with tokenSeparators

[domnikov-timofei]

Problem

When pasting text like Lucy,Jack into Select with mode="tags" and tokenSeparators,
the text is correctly split into tags, but the original pasted string remains in the input field.

Steps to reproduce

1. Use <a-select mode="tags" :token-separators="[',']" />
2. Paste Lucy,Jack into the input
3. Tags are created but Lucy,Jack remains visible in input

Solution

Changed order of operations in MultipleSelector.handleInput:

• Process onInputChange first (triggers token splitting, clears searchValue)
• Then sync targetValue with reactive inputValue state

Changes

• components/vc-select/Selector/MultipleSelector.tsx
