Caches the bot's own identity (auth.test) per token.
This is what fills Slink.Context's :bot_user_id: the transports prewarm
the cache (Socket Mode on connect, the Events API plug per request) and stamp
the cached id into the handler context, powering Slink.mentions_me?/1.
Reads never block and never touch the network — until the one-off auth.test
round-trip completes, bot_user_id/1 is nil. A failed fetch stays uncached,
so the next prewarm simply retries.
Summary
Functions
The cached bot user id for token, or nil if not (yet) known.
Returns a specification to start this module under a supervisor.
Fetch and cache the identity for token off-process, unless already cached.

Fetch and cache the identity for token off-process, unless already cached.
Fire-and-forget: the auth.test call runs under Slink.TaskSupervisor, so a
slow or failing Slack never blocks the caller (a transport). Safe to call on
every event — a cache hit is a single ETS read.
