DISCORD_ALLOWED_USERS="*" now means "allow everyone", matching the
SIGNAL_ALLOWED_USERS / DISCORD_ALLOWED_CHANNELS wildcard convention and
the value `claw migrate` emits. Previously _is_allowed_user did exact
ID matching only, so "*" matched no user and blocked every non-self
sender — a P1 with no workaround.
Three sites, all required for the fix to hold at runtime:
- _is_allowed_user: short-circuit when "*" is in the allowlist.
- connect(): exclude "*" from the intents.members trigger so the
wildcard does not request the privileged Server Members intent
(which can block the bot from coming online).
- _resolve_allowed_usernames: preserve "*" verbatim; otherwise it lands
in the username-resolution bucket, matches no member, and is silently
dropped from the set and env var on the first on_ready — quietly
undoing the fix.
Slash auth delegates to _is_allowed_user (auto-covered); component auth
already honors "*" on main.
