feat(swap): import .md files and webp transition from myst/current

Selective import from origin/myst/current (cf9c9b34):
- Add/update 255 .md files (full MyST conversion plus webp ref updates)
- Delete 175 PNG/JPG from docs/_static/images (webp twins already present)
- Delete 5 autotest topology.png (webp twins already present)

Preserved on swap (untouched):
- All .rst files (incremental swap pattern)
- conf.py, _ext/, _include/*.txt, .gitignore
- 115 canary md-*.md files
- 7 superpowers/specs/*.md design docs
- Logos vyos-logo.png / vyos-logo-icon.png (referenced by conf.py)

+## System configuration commands
+
+```{cfgcmd} set system ip disable-forwarding
+
+Use this command to disable IPv4 forwarding on all interfaces.
+```
+
+```{cfgcmd} set system ip disable-directed-broadcast
+
+Use this command to disable IPv4 directed broadcast forwarding on all
+interfaces.
+
+If set, IPv4 directed broadcast forwarding will be completely disabled
+regardless of whether per-interface directed broadcast forwarding is
+enabled or not.
+```
+
+```{cfgcmd} set system ip arp table-size \<number\>
+
+Use this command to define the maximum number of entries to keep in
+the ARP cache (1024, 2048, 4096, 8192, 16384, 32768).
+```
+
+```{cfgcmd} set system ip multipath layer4-hashing
+
+Use this command to use Layer 4 information for IPv4 ECMP hashing.
+```
+
+```{cfgcmd} set system ip import-table \<table-id\>
+
+Use this command to immport the table, by given table id, into the main RIB.
+```
+
+```{cfgcmd} set system ip import-table \<table-id\> distance \<distance\>
+
+Use this command to override the default distance when importing routers
+from the alternate table.
+```
+
+```{cfgcmd} set system ip import-table \<table-id\> route-map \<route-map\>
+
+Use this command to filter routes that are imported into the main table
+from alternate table using route-map.
+```
+
+
+### Zebra/Kernel route filtering
+
+Zebra supports prefix-lists and Route Maps to match routes received from
+other FRR components. The permit/deny facilities provided by these commands
+can be used to filter which routes zebra will install in the kernel.
+
+```{cfgcmd} set system ip protocol \<protocol\> route-map \<route-map\>
+
+Apply a route-map filter to routes for the specified protocol. The following
+protocols can be used: any, babel, bgp, eigrp, isis, ospf, rip, static
+
+:::{note}
+If you choose any as the option that will cause all protocols that
+are sending routes to zebra.
+:::
+```
+
+
+### Nexthop Tracking
+
+Nexthop tracking resolve nexthops via the default route by default. This is enabled
+by default for a traditional profile of FRR which we use. It and can be disabled if
+you do not want to e.g. allow BGP to peer across the default route.
+
+```{cfgcmd} set system ip nht no-resolve-via-default
+
+Do not allow IPv4 nexthop tracking to resolve via the default route. This
+parameter is configured per-VRF, so the command is also available in the VRF
+subnode.
+```
+
