ESP-IDF JSON Support - Custom Naming

Describe the bug With the VSCode plugin, I am looking to use the flasher_args.json functionality to read in a custom binary (containing NVS flash data).

AFAIK flasher_args.json is an internal idf framework file, and additional parameters cannot be easily added via a simple idf.py build command (I may be wrong, but haven't found much/any documentation on this).

To avoid conflicts, my workaround is to create a manual file called wokwi_flasher_args.json which will then:

• On build, copy ./wokwi_flasher_args.json to ./build/wokwi_flasher_args.json
• firmware: 'build/wokwi_flasher_args.json' is set

However, it looks like the current implementation may be checking for the exact path. The same file, with a different filename (within build) results in a simulation boot loop. It would be ideal if it could see it as a .json, and derive that it is a flasher_args from the extension - or is this a known issue with the functionality?

To Reproduce ESP-IDF project:

[wokwi]
version = 1
firmware = 'build/flasher_args.json'
elf = 'build/example_app.elf'

Works, however:

[wokwi]
version = 1
firmware = 'build/my_custom_flasher_args.json'
elf = 'build/example_app.elf'

Does not work.

Expected behavior I would like custom naming support for flasher_args.json, to avoid any internal conflicts with idf.py tooling.

Environment (please complete the following information):

• OS: Linux
• VSCode
• Wokwi Extension v2.5.3
