Use the text-control auto content size when calculating max-content width for primitive text input widgets. CSS Sizing treats cyclic percentage preferred sizes as initial values for non-replaced max-content contributions, so an `appearance: none` input with `width: 100%` should contribute its `width: auto` size instead of collapsing to zero. Keep the min-content path unchanged so the percentage-sized replaced element rule can still compress non-button-like input controls for flex automatic minimum sizing. Add coverage for an inline-flex control matching the GitHub file search layout.
