istrain-public: from-scratch build of a passive RF train detector

Public community release. The complete working system — DSP + decoders (scripts/),
web dashboard + API (dashboard/), container stack (docker/), config templates (config/) —
plus APOCALYPSE-EDITION.md, the full build guide for a human or a coding agent. GPLv3
(PyEOT dependency). Scrubbed of all secrets, internal IPs, hostnames, and location detail.
