- HTTP checks: use io.ReadAll with LimitReader instead of single Read()
to handle bodies spanning multiple TCP segments
- HTTP checks: enforce TLS 1.2 minimum, matching websocket and mikrotik
- Ping/credential jobs: use select/default for channel sends to prevent
goroutine leaks when result channel is full
- LLDP: check strconv.Atoi errors in IPv6 address parsing instead of
silently producing incorrect addresses
- SNMP: use comma-ok type assertions in snmpValueToString to prevent
panics from malformed device responses
- WebSocket: read handshake response line-by-line via bufio.Reader
instead of single conn.Read that could miss multi-segment responses
