Subject: refactor: Replace ad-hoc dispatch with FSM + driver architecture
 (#3434)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaces the tangled dispatch handler system (`tui/dispatch.rs`,
`tui/state.rs`) with a pure finite state machine + driver architecture.
The FSM handles all state transitions as explicit `(State, Event) →
(NewState, Effects)` mappings. The driver executes IO effects and
bridges the TUI to the FSM.
