Bug Description

The DiscordAccountSchema in zod-schema.providers-core.ts uses .strict() but is missing the agentComponents field. This field is:

1. Defined in the TypeScript type at types.discord.ts:301 as agentComponents?: DiscordAgentComponentsConfig
2. Actively read at runtime in discord/monitor/provider.ts:544-545
3. Used in tests at discord/monitor/provider.test.ts:87

Because the schema is .strict(), any user who sets channels.discord.agentComponents.enabled: true in their config YAML will get a validation error, even though the field is valid and used at runtime.

Steps to Reproduce

channels:
  discord:
    agentComponents:
      enabled: true

This config is rejected by validateConfigObject() with an unrecognized key error.

Expected Behavior

The config should be accepted, since agentComponents is a valid field defined in the TypeScript types and used at runtime.

Root Cause

Type/schema drift: agentComponents was added to the TypeScript types and runtime code but not to the Zod validation schema.
