' HTTP+JSON test harness, callable as GET /self-test from any CLI (curl,
' Invoke-WebRequest, etc.) - no cscript/PowerShell/WSH access to the VM
' required. Runs the same checks as tests/Test-Components.vbs, in-process,
' against the live registered components. Intentionally returns raw
' Err.Description in failure details: unlike Default.asp's own error
' handling (which must never leak internals to an arbitrary client), this
' route IS the diagnostics surface, so its whole job is to say what broke.
' This is a dev/test-milestone tool, not a production data endpoint -
' revisit whether it should be gated/removed during M6 hardening.
