ed78a100e2 feat: port session 05 — Subscription Index (sublist) 
Port trie-based subject matching engine (81 features, 74 tests).
Includes SubscriptionIndex with cache, wildcard matching (*/>),
queue subscription groups, reverse match, notifications, stats,
and subject validation utilities. Also adds minimal Subscription
and NatsClient stubs needed by the index.

  (Stop→SIGKILL, Quit→SIGINT, Reopen→SIGUSR1, Reload→SIGHUP), ResolvePids via pgrep,
  SetProcessName, Run/IsWindowsService stubs for non-Windows
- 11 tests (6 logger, 5 signal/service)
- WASM/Windows signal stubs already n/a
- All 141 tests pass (140 unit + 1 integration)
- DB: features 368/3673 complete, tests 155/3257 complete (9.6% overall)

b335230498 chore: scaffold .NET solution structure for Phase 6 
Creates the four-project .NET 10 solution (ZB.MOM.NatsNet.slnx):
- ZB.MOM.NatsNet.Server: main library with MEL, BCrypt.Net-Next, IronSnappy
- ZB.MOM.NatsNet.Server.Host: console host with Serilog + Microsoft.Extensions.Hosting
- ZB.MOM.NatsNet.Server.Tests: xUnit 2.9 / Shouldly / NSubstitute / BenchmarkDotNet
- ZB.MOM.NatsNet.Server.IntegrationTests: same test stack, separate project

Also adds Phase 6 porting plan and task-tracking JSON.

023a5ddb7e chore: complete phase 5 - verify all .NET mappings 
All verification checks passed: zero unmapped items, zero collisions,
all PascalCase naming, valid namespaces, all N/A items justified, all
tests targeting correct project. Fixed 8 non-PascalCase method names.
