fix: TUI CSI u key parsing and console escape sequence order

Browse Source 
- TUI: Add parseCSIuBytes to handle CSI u sequences that bubbletea
  v1.3.6 returns as []byte (unknownCSISequenceMsg). Parses codepoint
  and modifier bits to reconstruct key string for hotkey routing.
- Console: Reorder escape parser checks. Check 2-byte non-CSI
  sequences first, then CSI terminator only after ESC[ introducer.
  Fixes CSI u sequences being truncated at '[' byte (0x5b).
