9e050b140b cli: rename -reconnect-delay to -reconnect-delay-secs 
All time arguments now use -secs suffix with integer seconds for
consistency (-reconnect-delay-secs, -keepalive-timeout-secs).

1a397c363f tunnel: add -keepalive-timeout-secs for dead connection detection 
Tracks last server receive time (atomic) and runs a watchdog goroutine
that closes the connection if no data arrives within the timeout,
triggering reconnection. Also fixes Close() to guard Conn.Close()
inside sync.Once so concurrent/repeated calls are safe.

51824b830e netcfg: add -connmark flag for DNAT reply routing 
When VPN traffic is DNAT'd to local namespaces/VMs, reply packets have
a different source IP (namespace veth) so the policy route's
"from <VPN_IP>" rule doesn't match. CONNMARK marks all connections
arriving on the VPN interface and restores the mark on reply packets,
routing them back through the tunnel via fwmark rule.

New flag: -connmark (requires -policy-route-table)

17c1063e1f refactor: extract session/netcfg/tunnel, add mac/dhcp/policy-route flags 
- Split cmd/softether-go into main.go (flags, reconnect loop) and
  session.go (session lifecycle, DHCP orchestration)
- Extract network config to pkg/netcfg (TAP config, routing, DNS, policy routes)
- Move frame bridging to pkg/client/tunnel.go as Bridge() method
- Add -mac, -dhcp, -policy-route-table CLI flags
- Add SetMAC() to pkg/tap for deterministic DHCP assignments
- Update all docs to reflect new structure and flags
