tmux: enable truecolor + focus-events for TUI apps

Browse Source 
- Switch default-terminal from screen-256color to tmux-256color
  (better italics/undercurl/SGR support for nvim, Claude Code, etc.)
- Add terminal-features RGB for the common outer terminals so
  truecolor escape sequences pass through cleanly
- Enable focus-events so inner programs can redraw when the pane
  regains focus
