📝 Walkthrough

Walkthrough

The CLI derives --get configuration-field completions from protobuf descriptors. It supports snake_case and camelCase names, prefix filtering, sorted unique results, and unit-tested argument wiring.

Changes

Configuration field shell completion

Layer / File(s)	Summary
Descriptor-based field discovery meshtastic/__main__.py	The CLI derives configuration field names from LocalConfig and LocalModuleConfig descriptors in snake_case and camelCase, then filters them by prefix.
CLI completion wiring and validation meshtastic/__main__.py, meshtastic/tests/test_main.py	The --get argument uses _complete_config_fields. Tests verify field discovery, sorting, deduplication, prefix filtering, and completer assignment.
