- move the analysis server out of simtrace2_pysniff into simtrace_analyser; simtrace2_pysniff stays as the simtrace2-sniff replacement capture utility - new server CLI: simtrace-analyser-server; python -m simtrace_analyser (simtrace2-pysniff-server and python -m simtrace2_pysniff.server dropped) - simtrace2_pysniff lazy-imports hardware symbols, so the server no longer pulls PyUSB at startup; the GSMTAP/PCAP codecs work without libusb - version 2.0.0 everywhere (was 1.22.21); PWA SW cache simtrace-analyser-v54 - frontend: server name, clone URL and i18n strings updated; vendored-parser reference otaman -> SIMple - README/README_RUS reworked product-first (analyser first, utility second) - DB dir ~/.simtrace-analyser, /api status payload and hosted PWA unchanged
