[I] [BUG] Wildcard subscription matching not implemented — +/-# subscriptions never receive messages [shenyu]

Aias00 opened a new issue, #6851:
URL: https://github.com/apache/shenyu/issues/6851

   ## Description
   Subscriptions containing `+` (single-level) or `#` (multi-level) are stored under the literal wildcard string and never matched against published topic names; the matcher is an explicit TODO. `Publish.send` looks up `SubscribeRepository.get(topic)` with the literal published topic (plain `ConcurrentHashMap.getOrDefault` exact-key lookup).
   
   ## Location
   - `shenyu-protocol/shenyu-protocol-mqtt/src/main/java/org/apache/shenyu/protocol/mqtt/Subscribe.java:63` (`// todo Regular match`)
   - `shenyu-protocol/shenyu-protocol-mqtt/src/main/java/org/apache/shenyu/protocol/mqtt/repositories/SubscribeRepository.java:90-92`
   
   ## Impact
   Wildcard subscriptions never receive any message — a core MQTT feature is silently broken.
   
   ## Suggested fix
   Implement topic-filter matching per MQTT-4.7 (`+` single level, `#` multi-level at end) and match published topics against all stored filters on each PUBLISH.
