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. Error: × Operation interrupted ╭─[display_output hook:1:1] 1 │ if (term size).columns >= 100 { table -e } else { table } · ─┬ · ╰── This operation was interrupted ╰──── : example ctrlc interrupt status: false <-- NOTE status is false waiting for interrupt signal... ^Cinterrupt status: true peace.

nu-plugin-protocol
This crate provides serde-compatible types for implementing the Nushell plugin protocol. It is primarily used by the nu-plugin family of crates, but can also be used separately as well.
The specifics of I/O and serialization are not included in this crate. Use serde_json and/or rmp-serde (with the named serialization) to turn the types in this crate into data in the wire format.
