* fix(runtime): throw a descriptive error when raw mode is unsupported (Ink parity, G10)
Previously the raw-mode acquire path silently no-opped on a stdin where raw mode
is unsupported (non-TTY / isRawModeSupported false), so using useInput on such a
stdin did nothing with no diagnostic. Ink's handleSetRawMode (App.tsx:315-327)
instead throws immediately when enabling raw mode is unsupported, with two
distinct messages (default process.stdin vs a custom stdin) both pointing at the
isRawModeSupported docs.
StdinController.acquireRawMode now throws that two-message error on
!isRawModeSupported. The unguarded useInput path surfaces it (matching Ink's
use-input.ts, which calls setRawMode(true) ungated). useFocus now guards on
isRawModeSupported before acquiring (matching Ink's use-focus.ts), so focus
degrades to a safe no-op on a non-TTY rather than throwing. releaseRawMode keeps
its no-op guard — Ink only throws when enabling.
