config.json carried a raw apiKey byte-identical to DEEPSEEK_API_KEY in
~/.reasonix/.env, which config.toml already names properly via
api_key_env -- so the copy was redundant, not load-bearing. Removed it;
`reasonix doctor --json` still reports key_present=true for both
providers and the rest of the report is unchanged.
The remainder of config.json is machine-local state -- a generated
dashboard token, its port, and UI flags -- so ignore it rather than
track it. config.toml stays tracked and holds the portable config.
