Head commit for run: 5cfc7716524308bf56e72c88d239cbc37215b85b / wangjiahua.wjh <[email protected]> [ISSUE #10442] Optimize message properties encode/decode to reduce allocation Focuses on the properties encode/decode hot path (broker send + dispatch): - MessageDecoder.string2messageProperties: right-size HashMap from separator count instead of fixed capacity 128; intern well-known property keys via length-bucketed regionMatches (skip substring+hash); intern frequent values ("0","1","true","false","DefaultRegion"). - MessageDecoder.messageProperties2Bytes: direct UTF-8 byte serialization of Map entries, skipping the StringBuilder→String→getBytes round-trip. - MessageDecoder.bytes2messageProperties: parse directly from byte[] with ASCII key matching, skipping intermediate String allocation. - MessageDecoder.messageProperties2String: reuse ThreadLocal StringBuilder with capacity cap to bound per-thread memory. - MessageConst: add STRING_INTERN_MAP and STRING_INTERN_BY_LEN for canonical key interning. - MessageExtBrokerInner: add propertiesData byte[] cache field to short-circuit propertiesString→byte[] re-encoding on the write path.
