PR Summary

• Introduction of a new file for Nervos Network support A file named messages-nervos.proto is added to help define protocols used when interacting with the Nervos Network.

• Adjustments to several files for expanded Nervos Network compatibility Several existing files, including common/protob/messages.proto, core/src/trezor/enums/MessageType.py, and core/src/trezor/enums/__init__.py, are updated to include new message types that facilitate interactions with Nervos Network.

• Implementation of message definitions and handlers for Nervos Updates are made to core/src/trezor/messages.py, legacy/firmware/fsm.c, and legacy/firmware/fsm.h, alongside the addition of fsm_msg_nervos.h, nervos.c, and nervos.h files, to properly handle communication with the Nervos Network.

• Adjustments to firmware’s Makefiles for Nervos Modifications in legacy/firmware/Makefile and legacy/firmware/protob/Makefile are done to include new Nervos-related sources and protocol buffer options files. Additionally, a messages-nervos.options file is added to help with the control of maximum sizes of protocol buffer messages for Nervos.

• Addition of a file symlink for ease in Nervos message handling A symlink named messages-nervos.proto was added in legacy/firmware/protob/ directory that leads to common/protob/messages-nervos.proto for easier Nervos message handling.

• Support for Nervos-specific CLI commands For facilitating command-line interaction with the Nervos Network, nervos.py is introduced to the python/src/trezorlib/cli/ directory. In parallel, trezorctl.py in the same directory is updated to support these new Nervos commands.

• Introduction of new message types in messages.py New message types NervosGetAddress, NervosAddress, NervosSignTx, NervosSignedTx are included in the messages.py file with a new nervos.py module that provides functions get_address and sign_tx for more flexible interaction with the Nervos blockchain.
