Themes as standalone config files + configurable shadow + dim unfocused + resize content-loss fix

Browse Source 
- Theme is now a runtime struct loaded from its own TOML file
  (theme = "themes/dark.toml" in config.toml, like panels), all
  fields optional with built-in defaults; ships themes/dark.toml and
  themes/light.toml
- shadow = true/false in config.toml, shadow_color per theme
- dim_unfocused (per theme): unfocused window content is dimmed
- BUGFIX: resizing a window no longer erases its content and history —
  the vt100 parser was recreated on every resize; now uses
  screen_mut().set_size() which preserves the grid and scrollback
- New integration check: window content survives mouse resize (20/20)
