Joseph Doherty 88b1391ef0 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.

# Session 14: Routes
## Summary
Inter-server routing — how NATS servers form a full mesh cluster and route messages between nodes.
## Scope
| Go File | Features | Feature IDs | Go LOC |
|---------|----------|-------------|--------|
| server/route.go | 57 | 28952951 | 2,988 |
| **Total** | **57** | | **2,988** |
## .NET Classes
- `RouteHandler` — route connection management
- `ClientConnection` (partial — route-specific methods, 25 features from client.go already counted in S08)
## Test Files
| Test File | Tests | Test IDs |
|-----------|-------|----------|
| server/routes_test.go | 70 | 27962865 |
| **Total** | **70** | |
## Dependencies
- Session 01 (Foundation Types)
- Session 07 (Protocol Parser)
- Session 08 (Client Connection)
- Session 09 (Server Core Part 1)
## .NET Target Location
- `dotnet/src/ZB.MOM.NatsNet.Server/Routing/`
## Notes
- Route connections are `ClientConnection` instances with special handling
- Protocol includes route-specific INFO, SUB, UNSUB, MSG operations
- Cluster gossip and route solicitation logic lives here
