feat: add timestamp tracking to flows with first_seen_at/last_seen_at/observed_at fields across all collectors

Add FIREWALL_LOG_TS_RE regex to parse timestamps from firewall log lines, implement firewall_log_seen_at to extract and convert log timestamps to UTC ISO format, add first_seen_at/last_seen_at/observed_at fields to flows in collect_packet_flows (AF_PACKET collector) with timestamp updates on flow aggregation, add timestamp fields to collect_flows (conntrack collector) and parse_firewall_log_line (

+Agent version `0.2.1` reports host/interface counters, VMID hints from Proxmox interface names, real packet-derived IPv4 TCP/UDP/ICMP flows from VM interfaces, conntrack flow records when available, recent kernel firewall log drops/rejects, pve-firewall status, and an nftables ruleset hash. NexaFabric maps flow source/destination IPs back to workloads through IPAM, so VM/LXC details can show observed and blocked traffic once guest IPs have been discovered. Blocked traffic visibility depends on Proxmox/kernel firewall logging being enabled for the rule or default drop that rejected the packet.

+The default agent config enables the packet flow collector:
+
+```json
+{

+  "packet_flow_window_seconds": 10,

+The collector runs as root through the Linux `AF_PACKET` interface and attaches to Proxmox VM interfaces such as `tap100i0` and `fwln100i0`. It aggregates locally before sending data to NexaFabric; packet payloads are not stored or uploaded.

+# NexaFabric eBPF helper contract
+
+Agent 0.3.0 can call an optional helper binary at `/opt/nexafabric-agent/nexafabric-ebpf`.
+The repository includes a dependency-free Go helper source at `nexafabric-ebpf.go`.
+
+The first implementation uses Linux raw packet sockets on the selected VM/LXC interfaces and prints the same JSON contract that a tc/eBPF implementation should print. This keeps the helper installable on Proxmox immediately while preserving the agent integration point for a later kernel eBPF loader.
+
+The helper is invoked as:
+
+```sh
+nexafabric-ebpf --json --limit 1500 --duration 10 --interfaces tap100i0,fwln100i0
+```
+
+It must print JSON to stdout:
+
+```json
+{
+  "flows": [
+    {
+      "source_ip": "172.16.0.10",
+      "destination_ip": "172.16.0.20",
+      "protocol": "tcp",
+      "source_port": 443,
+      "destination_port": 53020,

+  "diagnostics": {
+    "attach_mode": "af_packet_raw_socket",
+    "interfaces_attached": ["tap100i0"]
+  }
+}
+```
+
+The Python agent merges these flows with firewall-log, packet, and conntrack fallback collectors.
