Method submit

internal/tui/model.go:575–608

submit commits a user prompt. sendText is the expanded form sent to the LLM (chip labels replaced by their original paste content); echoText is the collapsed form shown in scrollback so the chat doesn't swallow 80 lines of pasted log every turn; entry is the history snapshot replayed by ↑/↓, includi

(sendText, echoText string, entry promptEntry)
