Enhance tmux window-status formatting with explicit colors, padding, and reset

[limijd]

Motivation

• Improve the visual appearance and consistency of tmux window labels by making foreground/background colors and padding explicit.
• Ensure the status formatting for active and inactive windows does not bleed styles into the rest of the status bar by adding explicit style resets.
• Preserve the existing behavior of showing a green ⚡ indicator when a window is @working or @running while making the indicator spacing and colors consistent.

Description

• Updated setw -g window-status-format in both portable/tmux.conf and tmux/tmux.conf to include explicit #[fg=...] and #[bg=...] declarations, added surrounding spaces for padding, and appended #[default] to reset styles.
• Updated setw -g window-status-current-format in both files to likewise include explicit foreground/background/bold attributes, padding, and #[default] reset for the current window label.
• Adjusted the inline conditional lightning indicator styling to include a preceding space and consistent foreground resets so the indicator renders in green and returns to the configured label color cleanly.

Testing

• No automated tests were run for this configuration-only change.
