Create or update a custom rate limit for specific identifiers, bypassing the namespace default.
Use this to create premium tiers with higher limits, apply stricter limits to specific users, or implement emergency throttling.
Important: Overrides take effect immediately and completely replace the default limit for matching identifiers. Use wildcard patterns (e.g., premium_*) to match multiple identifiers.
Permissions: Requires ratelimit.*.set_override or ratelimit.<namespace_id>.set_override
