[Rizzener]

Adds an input_chat_str command, mirroring input_chat but storing the raw player input as a string argument instead of parsing it as a number via FastExpressionParser.

Usage

on_click:
  - input_chat_str:
      param: 'str_result'
      on_pass:
        - '&aYou said: {str_result}'
      on_failed:
        - '&cInput cancelled'

• Input via chat or command; the leading / from command input is stripped
• null input (timeout/quit/override) triggers on_failed, same as input_chat
• New handler: PlayerStringInput, an exact structural mirror of PlayerNumberInput (same codec pattern, tracer style, error message)
• Registered in Commands#decode next to input_chat
• Example added to menu/debug.yml

Verified: mvn clean package passes; codec decode matrix (valid config, missing fields, int coercion) behaves identically to input_chat.
