bubbles/v2 textinput truncates the placeholder to its first rune when the input width is 0 (the default): it sizes the placeholder buffer to Width()+1 and early-returns after the first character. Set a non-zero width on every text input (defaultInputWidth) and resize inputs responsively to the terminal on WindowSizeMsg via FormStep.SetWidth, so placeholders render in full and inputs fill the available width. Adds a regression test asserting the placeholder renders past its first rune. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
