Mode widget colors reset at widget boundary — no way to style other widgets per mode

[Diaoul]

Description

Colors set in mode_* format strings are reset at the {mode} widget boundary. This means subsequent content in format_left / format_right / format_center does not inherit the colors from the mode widget, making it impossible to dynamically style other widgets (like {session}) based on the current mode.

Steps to Reproduce

plugin location="..." {
    format_left   "{mode}{session} {tabs}"

    mode_locked "#[bg=#31748f,fg=#191724,bold]  LOCKED "
    mode_tmux   "#[bg=#eb6f92,fg=#191724,bold]  COMMAND "
}

Expected: {session} renders on the #31748f (or #eb6f92) background set by the mode widget, since no color reset is specified between {mode} and {session}.

Actual: Colors reset to terminal defaults after {mode}. The session name renders with default terminal colors (white on black), not the mode's background.

I also tested with plain text between {mode} and {session} — same result: terminal default colors.

Use Case

I'd like the entire left block (icon + session name) to change background color when switching modes (e.g., pine background in locked mode, red in tmux/command mode). Currently only the content inside {mode} can change color per mode.

Possible Solutions

1. Preserve colors across widget boundaries — don't reset colors after rendering {mode}, let them carry into the rest of the format string
2. Mode-aware color variables — expose something like {mode_bg} / {mode_fg} that can be used in format_left / format_right (e.g., "#[bg={mode_bg}]{session}")
3. Allow widget placeholders inside mode_* — expanding {session} inside mode format strings would let users compose mode-dependent blocks
