separatorLength now derives value from window layout on each call;
hoist to local as it cannot change within single repaint

 CHANGELOG
 =========
 
+0.74.1
+------
+- 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
+    - Fixed ghost characters and misplaced colors inside Zellij by using CHA instead of CR + CUF for horizontal cursor movement (#4858, zellij-org/zellij#5370)
+    - Fixed cursor restoration on exit with `--height --no-clear` inside Neovim terminal by using DECSC/DECRC instead of `CSI s`/`CSI u`
+- nushell: fixed deprecation error of `str downcase` on nushell 0.114.0 or above (#4857) (@sim590)
+- Each release now includes `.deb` packages for easy installation on Debian-based distros (#4859)
