CydandClaude Fable 5 8730b9b966 XP11: single net40 binary runs on XP SP3 through Windows 11
Merge TeslaLauncherService (Session 0) + TeslaLauncherAgent (tray) into one
userland TeslaLauncher.exe. The split existed only to work around Vista+
Session 0 isolation; running everything in the auto-logged-in admin session
needs no service, no named pipe, and no flat<->wire conversion layer. The
original Elsewhen software was likewise a single binary.

net40 is the newest framework XP SP3 can install, and net40 assemblies load
in-place on the 4.8 runtime in Win10/11 -- one exe covers both.

- Contract: multi-target net48;net40. The net40 leg of PodRpcProtocol uses
  Newtonsoft.Json (STJ has no net40 target); JSON is shape-identical on the
  wire, and the request reader keeps date strings raw so Ping echoes
  byte-identically. Console keeps the untouched net48/STJ leg.
- MiniZip.cs: central-directory ZIP extractor (stored/deflate/ZIP64) since
  net40 has no ZipFile; zip-slip guarded.
- SecureConfig: RSACryptoServiceProvider instead of RSA.Create (net46+),
  no leaveOpen BinaryWriter/Reader, struct instead of ValueTuple, and no
  SetCompatibleTextRenderingDefault on the passcode thread (the merged app
  already has a form). netsh "interface ip" syntax was already XP-correct.
- Volume: nircmd -> CoreAudio (Vista+) -> winmm waveOutSetVolume (XP).
- Paths: CommonApplicationData resolved per-OS (XP has no C:\ProgramData);
  launcher log moved next to the key/config in the data dir.
- install.bat: dual-OS (cacls/icacls, netsh firewall/advfirewall, dism and
  UAC/notification steps skipped on XP, .NET 4.0 redist check, XP DHCP reset
  via netsh); no service registration -- HKLM Run key + auto-login on both;
  RegisterApplicationRestart supplies crash-restart on Vista+.
- Bench switches: /skipconfig, /port:NNNN.

Verified: Console + diff suite (103 tests) still green on the net48 leg;
E2E smoke test drove the net40 launcher over real TCP with the Console's own
PodManagerConnection (STJ client vs Newtonsoft server) -- Ping echo, volume,
app registry, launch/kill/watch, InstallProduct zip transfer + extract, and
uninstall orphan cleanup: 17/17 pass.
