Struct promptInput

internal/tui/prompt.go:27–32

promptInput wraps bubbles/textarea with an atomic-chip model. A large paste collapses into a single inline label [Pasted text +N lines] that acts as one character for cursor moves and deletion; the original text lives in store, keyed by id, and is expanded back by Value() on LLM submission.

// character for cursor moves and deletion; the original text lives in store,
// keyed by id, and is expanded back by Value() on LLM submission.
type promptInput struct {
	ta     textarea.Model
	store  map[int]chipContent
	spans  []chipSpan
	nextID int
}

// chipContent is the payload behind a chip, kept in store by id so the visible
// label can collapse while the real text survives for Value() and replay.
