Subject: [PATCH] fix: import CHANNEL_IDS from leaf module to avoid TDZ on init
 (#48832) (#60061)

schema.ts and validation.ts imported CHANNEL_IDS from channels/registry.js,
which re-exports from channels/ids.js but also imports plugins/runtime.js.
When the bundler resolves this dependency graph, the re-exported CHANNEL_IDS
can be undefined at the point config/validation.ts evaluates (temporal dead
zone), causing 'CHANNEL_IDS is not iterable' on startup.

Fix: import CHANNEL_IDS directly from channels/ids.js (the leaf module with
zero heavy dependencies) and normalizeChatChannelId from channels/chat-meta.js.

Fixes #48832
