neovim: Revamp statusline config

[Lehmanator]

Statusline

Using lualine.nvim with winbar & tabbar enabled.

Goals

• Match zsh shell prompt.
• Match readline prompt.
• Match tmux status lines.
• Organized similarly to VSCode.
• Don't deviate too far from standard Neovim.

Considerations

• What can I show in tmux statusline instead
  • user@host
  • path

Changes

• Mode indicator: Abbreviate (only when cramped?)
• Mode indicator: Sentence case (when not abbreviated)
• Remove one of the top statusbars

Move Segments

• VCS changes: Next to VCS branch segment
• Progress: Share segment w/ cursor position (line/char x,y)
• Filename & path: Top bar OR left of VCS changes / branch (matching shell prompt)
