Release: fsm-toolkit v0.9.5

fsm-toolkit is a Go toolkit for designing and analysing finite state machines. It provides a CLI tool (fsm) and a full TUI editor (fsmedit) supporting DFA, NFA, Mealy, and Moore machines — with multi-machine bundles, cross-machine linking, and a component system backed by reusable class libraries.

https://github.com/ha1tch/fsm-toolkit#readme

This is the biggest release since the project's inception bringing a component-oriented workflow to FSM design. You can now drag 74xx-series digital logic parts from a library drawer, assign typed properties to states, link machines into bundles, and manage it all from the TUI. Builds and releases for 12 platforms are now fully automated.
