Add bridge name column to --list-networks

Browse Source 
list_networks_command() now includes each network's bridge name
(recomputed via bridge_name(), not stored -- it's already a pure
deterministic function of the network name), tab-aligned the same way
as the existing name/kind/subnet columns, positioned before the
trailing unaligned IPv6 column. Useful for correlating a network entry
with its live host-side state (`ip link show <bridge>`,
`iptables -t nat -L`) without recomputing the hash by hand.

Verified as root via the doas rule against a fresh extern and intern
network.

| `--delete-volume <name>` | Remove a named volume from the config. The host directory is left untouched. |
| `--delete-volume-full <name>` | Like `--delete-volume`, but also recursively deletes the volume's host directory. |
| `-n, --network <name>` | Create/manage a persistent named network: requires exactly one of `--extern` (a real Linux bridge in the host's own namespace, with NAT/forwarding set up so containers on it reach the host's real network) or `--intern` (a bridge inside its own dedicated, routeless namespace, only reachable by other containers on the same network). `--subnet <cidr>` overrides the auto-allocated IPv4 range (`10.168.0.0/24`, incrementing per network); `--no-ipv6` disables (and `--subnet6 <cidr>` overrides) the auto-allocated IPv6 range, on by default. `--no-veth` forces the tap+relay join fallback even on a kernel that supports veth (useful for testing that path; it's otherwise chosen automatically whenever the running kernel lacks veth support). With `--run`, instead joins `<name>` to the container as its own `eth<N>` interface with an address from the network's subnet; repeatable, no membership limit. Root-only for now. **Known gap**: on a network joined via the tap+relay fallback, peer-to-peer connectivity works, but reaching the network's own gateway (and thus the outside, for `extern`) does not yet — root cause unconfirmed, see [`docs/networking-design.md`](docs/networking-design.md). |

| `--list-networks` | List all named networks (see `-n/--network`) with their kind, IPv4 subnet, bridge name, and IPv6 subnet (or `(no ipv6)`). |
| `--delete-network <name>` | Remove a named network from the config. |
| `-p, --port-forward [<network>:]<host-port>:<container-port>` | With `--run`, forward a TCP port from the host into the container. `<network>` is optional, defaulting to the container's sole `--extern` network (an error if it joined more than one without specifying). Repeatable. Reachable via the host's real, externally-facing IP; `localhost`/loopback access has a known NAT-hairpinning limitation (see [`docs/networking-design.md`](docs/networking-design.md)). |
| `--list-processes` | List running `--run` sessions found by their pid files under `$XDG_STATE_HOME/slocker-lite/run/`, with their pid, container name, and status (`running` or `exited`). |
