Add window levels, status bar, UTF-8 input, charset conversion

- Isolated window levels with 500-line scrollback per window
  - Window 1: status + private messages
  - Windows 2-9: channels
- Status bar showing window, channel, nick prefix, channel modes
- Automatic charset conversion (UTF-8/UTF-16 -> ISO-8859-1 on wire)
- UTF-8 aware input editing with Ctrl-A/E/U/K/Y
- CTCP VERSION reply with real OS info from uname()
- Real name from passwd GECOS field
- SIGWINCH handling for terminal resize
- Ctrl-C quit confirmation (y + Enter)
- /whois, /wii, /mode, /quit with default reason
- Green prompt, timestamps on all messages

 ## Window Workflow
 
-1. Press ESC+3 to switch to window 3
+1. Press ESC+2 to switch to window 2
 2. `/join #channel` — the channel is bound to that window
-3. Press ESC+4, `/join #other` — second channel on window 4
+3. Press ESC+3, `/join #other` — second channel on window 3
-4. ESC+1 to check status, ESC+2 for private messages
+4. ESC+1 to check status and private messages
 
 Each window maintains its own scrollback. Switching redraws the full history.
