[BUG] GeneralContextPlugin NPE on null cached handle

[Aias00]

• severity: High
• files: shenyu-plugin/shenyu-plugin-proxy/shenyu-plugin-rpc/shenyu-plugin-general-context/src/main/java/org/apache/shenyu/plugin/general/context/GeneralContextPlugin.java:54
• description: doExecute calls obtainHandle(CacheKeyUtils.INST.getKey(rule)) and immediately dereferences .isEmpty() without a null check. CommonHandleCache.obtainHandle returns null on cache miss. Every other plugin in this set (ContextPathPlugin:55, RewritePlugin:68, etc.) guards with Objects.isNull(handle) before use; GeneralContextPlugin is the sole exception.
• impact: NullPointerException at runtime — request fails with 500 instead of passing through the chain.
• suggested_fix: Add if (Objects.isNull(generalContextHandleMap) || generalContextHandleMap.isEmpty()) { return chain.execute(exchange); } before line 54.
• confidence: High
• related_existing: none
