Plugin no longer throws during register() when API key is missing.
Instead it registers successfully, logs a clear setup message with
the exact command to run, and disables memory features until configured.
Before: openclaw plugins install -> register() throws -> gateway logs error
After: openclaw plugins install -> registers ok -> logs setup instructions
Users see:
openclaw-mem0: API key not configured. Memory features are disabled.
To set up, run:
openclaw config set plugins.entries.openclaw-mem0.config.apiKey "m0-your-key"
openclaw gateway restart
