ThereMaxi v1.0.0

First release of this fork, and the first version that runs on a current Linux distribution.
Tested on Ubuntu 26.10 with perl 5.40.1 and GTK 2.24.33.

Fixed

• File::Pid->running calls kill(0, undef) when no pidfile exists yet, which is a fatal error
  since perl 5.36 ("Can't kill a non-numeric process ID"). The program died on every fresh start
  before showing a window. A missing pidfile now means "not running".
• bless {}, "$base::$self" in lib/Controller.pm interpolates as the variable ${base::}
  followed by $self, so every controller was blessed into a package that does not exist
  ("Can't locate object method "define" via package "_085"").

Added

• README.md with dependency instructions for current Ubuntu, where the perl GTK2 bindings are no
  longer packaged and have to be built from CPAN, plus troubleshooting notes.
• CLAUDE.md, an architecture overview of the code.
• This changelog and a GitHub workflow that publishes a release when a v* tag is pushed.

Known limitations

Communication with actual hardware has not been re-tested since the port — the GUI, the preset
decoder and the library round-trip have. Reports from Theremini owners are welcome.
