This PR will close #13501 # Description This PR expands on [the relay of signals to running plugin processes](https://github.com/nushell/nushell/pull/13181). The Ctrlc relay has been generalized to SignalAction::Interrupt and when reset_signal is called on the main EngineState, a SignalAction::Reset is now relayed to running plugins. # User-Facing Changes The signal handler closure now takes a `signals::SignalAction`, while previously it took no arguments. The handler will now be called on both interrupt and reset. The method to register a handler on the plugin side is now called `register_signal_handler` instead of `register_ctrlc_handler` [example](https://github.com/nushell/nushell/pull/13510/files#diff-3e04dff88fd0780a49778a3d1eede092ec729a1264b4ef07ca0d2baa859dad05L38). This will only affect plugin authors who have started making use of https://github.com/nushell/nushell/pull/13181, which isn't currently part of an official release. The change will also require all of user's plugins to be recompiled in order that they don't error when a signal is received on the PluginInterface. # Testing ``` : example ctrlc interrupt status: false waiting for interrupt signal... ^Cinterrupt status: true peace.

Nushell REPL
This directory contains the main Nushell REPL (read eval print loop) as part of the CLI portion of Nushell, which creates the nu binary itself.
Current versions of the nu binary will use the Nu argument parsing logic to parse the commandline arguments passed to nu, leaving the logic here to be a thin layer around what the core libraries.
