pyte.screens.Char is a namedtuple (immutable), so fields can't be
mutated directly. Also 'width' doesn't exist — the correct field is
'blink'. Now creates new Char(...) objects for buffer restoration.
Fixes server switching being completely broken (AttributeError on save).

Save complete pyte screen state (characters, colors, attributes,
cursor position, modes) via pickle serialization instead of just
plain text. Restore via direct buffer manipulation + full redraw.
Fixes broken/garbled layout when switching between servers.

Instead of unconditionally resetting the terminal, reused sessions
now restore the saved screen content from the session pool.
