nx_hr_visitor_log.nx

nx_hr_visitor_log.nx -- NISHI HR, rung C: drive the front desk from REAL request logs. Parses a daemon access log (one request per line: `ip <TAB> path <TAB> user-agent`), aggregates per-IP request counts over the window, classifies each distinct visitor via hv_classify (rate + bot-UA + lists), writes a verdict report, and AUTO-BLOCKLISTS the ones it BLOCKs (so the next request is dropped at the door). This turns the visitor policy from a static list into BEHAVIOR-driven enforcement. Composes nx_hr_visitor. (Per-path anomaly + log rotation + dedup of the auto-blocklist = later rungs; this is the core behavior sweep.) license_tier: ORIGINAL
