PR #52 - Replace deprecated indirect object syntax (e.g. `new IO::Pty`) with direct method calls (`IO::Pty->new`). Perl 5.36+ disables indirect object calls, so this fixes forward compatibility.
Improvements:
PR #53 - Add clone_winsize_from() test coverage (7 new tests) covering basic clone between slave ttys, non-tty master fast path, croak on non-tty source, and pixel dimension preservation.
Maintenance:
PR #52 - Regenerate README from POD to fix stale version.
PR #53 - Modernize `use vars` to `our` declarations in Tty.pm and Pty.pm. Add missing `use warnings` to Pty.pm.
