Organize documentation by moving requirements (HighLevelReqs, Component-*,
lmxproxy_protocol) to docs/requirements/ and test infrastructure docs to
docs/test_infra/. Updates all cross-references in README, CLAUDE.md,
infra/README, component docs, and 23 plan files.
Set 30-second report interval with 60-second absolute timeout for offline detection.
Define error rates as raw counts per interval (reset after each report). Script errors
include all failure types. Automatic online recovery on first received report. Flat
snapshot report structure.
