feat: port session 07 — Protocol Parser, Auth extras (TPM/certidp/certstore), Internal utilities & data structures

Session 07 scope (5 features, 17 tests, ~1165 Go LOC): - Protocol/ParserTypes.cs: ParserState enum (79 states), PublishArgument, ParseContext - Protocol/IProtocolHandler.cs: handler interface decoupling parser from client - Protocol/ProtocolParser.cs: Parse(), ProtoSnippet(), OverMaxControlLineLimit(), ProcessPub/HeaderPub/RoutedMsgArgs/RoutedHeaderMsgArgs, ClonePubArg(), GetHeader() - tests/Protocol/ProtocolParserTests.cs: 17 tests via TestProtocolHandler stub Auth extras from session 06 (committed separately): - Auth/TpmKeyProvider.cs, Auth/CertificateIdentityProvider/, Auth/CertificateStore/ Internal utilities & data structures (session 06 overflow): - Internal/AccessTimeService.cs, ElasticPointer.cs, SystemMemory.cs, ProcessStatsProvider.cs - Internal/DataStructures/GenericSublist.cs, HashWheel.cs - Internal/DataStructures/SubjectTree.cs, SubjectTreeNode.cs, SubjectTreeParts.cs All 461 tests pass (460 unit + 1 integration). DB updated for features 2588-2592 and tests 2598-2614.
