fix(groq): use Config class instead of hardcoded config.json (#136)

Config class writes YAML (config.yaml), but xiaoyuzhou.py, cli.py, and
transcribe.sh were hardcoded to read config.json (JSON format). Users who
configured groq-key via 'agent-reach configure' would not have their key
detected because the wrong file was being read.

Fixes #128 (related to config loading)
