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)

+# Multicast
+
+In order to influence Multicast {abbr}`RPF (Reverse Path Forwarding)` lookup,
+it is possible to insert into zebra routes for the Multicast
+{abbr}`RIB (Routing Information Base)`. These routes are only used for RPF
+lookup and will not be used by ZEBRA for insertion into the kernel or for
+normal RIB processing. As such it is possible to create weird states with
+these commands.
+
+Use with caution. Most of the time this will not be necessary.
+
+```{cfgcmd} set protocols static mroute \<subnet\> next-hop \<address\> [distance \<distance\>]
+
+Insert into the Multicast RIB Route `<subnet>` with specified next-hop.
+The distance can be specified as well if desired.
+```
+```{cfgcmd} set protocols static mroute \<subnet\> next-hop \<address\> disable
+
+Do not install route for `<subnet>` into the Multicast RIB.
+```
+```{cfgcmd} set protocols static mroute \<subnet\> interface \<interface\> [distance \<distance\>]
+
+Insert into the Multicast RIB Route `<subnet>` with specified `<interface>`.
+The distance can be specified as well if desired.
+```
+```{cfgcmd} set protocols static mroute \<subnet\> interface \<interface\> disable
+
+Do not install route for `<subnet>` into the Multicast RIB.
