refactor: modernize aliases and clean up LESS flags

- Replace fgrep/egrep aliases with grep -F/grep -E (POSIX deprecated
  the standalone fgrep/egrep commands)
- Rename gdb alias to gdbr (gdb auto-started with args is a
  convenience shortcut, not a replacement for plain gdb)
- Remove LESS -X flag (legacy workaround for old less versions that
  didn't properly use alternate screen)
