• M: ChannelsSchema now .passthrough(), so typos/unknown channel keys no longer fail validation (silently ignored). If goal is plugin channel keys, consider validating passthrough keys against plugin registry or emitting warnings. src/config/zod-schema.providers.ts
• M: validateConfigObjectWithPlugins now runs on every config read/ update and always loads plugin registry; with plugins enabled by default this imports at least memory-core. Any broken plugin import or missing deps now makes config reads fail for unrelated commands. Consider gating plugin validation to when plugin config is present or making plugin errors non-fatal for read-only commands. src/ config/validation.ts

I chose to hard-fail on purpose, so people don't shoot themselves in the foot of things like "magical denylist setting that does not exist".

Landed via temp rebase onto main.
