Hide default separator when a border separates input from list

Browse Source 
- Applies when adjacent section (header, header lines, or list) draws
  border line facing input section

    # No separator below header border
    fzf --style full --input-border none --header foo

    # Separator shown; nothing separates input from list
    fzf --style full --input-border none --header foo --no-header-border

- Evaluated dynamically so change-header/toggle-header update it
- Inline header is drawn inside list border and not adjacent to input;
  decide from section actually next to it
- Separator is kept when a preview window can be at 'next' position,
  right next to the input section

------
- The default separator on the info line is no longer shown when the input section is already visually separated from the list section by a border line
```sh
# No separator shown below the header border
fzf --style full --input-border none --header foo
# Separator shown; no border separates the input section from the list section
fzf --style full --input-border none --header foo --no-header-border
```
- Rendering improvements
- Each frame is now wrapped in synchronized update mode (mode 2026) to reduce flickering on supported terminals
- Reduced rendering output by 10-23% by skipping redundant SGR sequences
