Fix: km config shows entire configuration, not just one node (#1094)
## Problem `km config` was calling `Initialize()` which forced node selection, making it show only one node instead of the entire configuration. **Before:** ```bash $ km config { "nodeId": "personal", # Only showed selected node "access": "Full", ... } ``` **After:** ```bash $ km config { "nodes": [ # Shows ALL nodes { "nodeId": "personal", ... } ], "cache": { # Shows cache config "embeddingsCache": {...} } } ``` ## Solution - `ConfigCommand` no longer calls `Initialize()` (no node selection needed) - Uses `GetConfig()` to access the injected config directly - Default behavior shows entire config (all nodes + cache) - `--show-nodes` and `--show-cache` flags still work ## TDD Approach 1. ✅ Test written first (RED) - verified it failed 2. ✅ Code fixed (GREEN) - test now passes 3. ✅ All 262 tests passing (185 Main + 77 Core) ## Changes - Add `ConfigCommandTests` with multi-node config verification - Update `ConfigCommand` to skip `Initialize()` for config queries - Add `BaseCommand.GetConfig()` protected method ## Test Results - ✅ 262 tests passing (185 Main + 77 Core) - ✅ Zero failures, zero skipped - ✅ Zero regressions
