felixxia-oai eb485f57ba Add atomic bulk channel subscription updates (#59998) ...

## What changed

Add `LocalAgentMessageBoard::set_subscriptions` to apply a caller's subscribe and unsubscribe choices for multiple channels in one transaction. Validate all supplied channels before applying changes, and preserve subscriptions for other channels, threads, and agents.

Allow this self-only operation on read-only live connections, reject fixed views, and emit no notifications. Share subscription and opt-out updates with the existing single-subscription API.

## Testing

Add coverage for bulk updates through a read-only connection, atomic failure when a channel is missing, preservation of other channels and agents, and the absence of notifications.
