This commit addresses three related issues in the CLI config and setup commands:
1. Issue #531: Fix config list apiKey masking
- maskApiKeys() now checks for 'apiKey' instead of 'apiKeyEnv'
- Updated tests to use apiKey field throughout
2. Issue #532: Add config set key validation
- Reject unknown top-level keys with helpful error messages
- Reject unknown nested fields in providers/models/agents
- Reject incomplete paths and nested paths on scalar keys
- Added VALID_CONFIG_KEYS schema and validateConfigKey() function
3. Issue #533: Fix agent name double-prefix in setup
- mergeConfig() now uses _agentNameFromBinary() to normalize agent names
- 'uwf-hermes' input now produces 'hermes' key with 'uwf-hermes' command
- Added tests for prefixed agent names
All tests passing, no regressions.
