Settings validator adds a rule requiring some values to be whole numbers of "character cells"

What

Claude Code's settings validation now includes a new rule for certain configuration keys, requiring their value to be a finite whole number within a set range, described in terms of "character cells". This is separate from the existing rule that validates color-string settings.

Why

This lets Claude Code catch invalid values earlier for settings that must be sized in character cells, giving a clearer error instead of accepting a malformed value.
