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)

+# Running on VMware ESXi
+
+## ESXi 5.5 or later
+
+`.ova` files are available for supporting users. You can also set up VyOS
+using a generic Linux instance by attaching the bootable ISO file and
+installing using the `install image` command.
+
+:::{NOTE}
+Previous issues have been documented with GRE/IPSEC tunneling
+using the E1000 adapter on VyOS guests. Use the VMXNET3 adapter instead.
+:::
+
+### Memory Contention Considerations
+
+When the underlying ESXi host reaches approximately 92% memory utilization,
+it begins the balloon process to reclaim memory from guest operating systems.
+This creates artificial memory pressure through the `vmmemctl` driver. Because
+VyOS does not have a swap file by default, this pressure cannot move memory
+data to a paging file. Instead, it consumes memory and forces the guest into
+a low memory state with no recovery option. The balloon can expand to 65% of
+guest allocated memory, so a VyOS guest using more than 35% of memory can
+encounter an out-of-memory situation and trigger the kernel `oom_kill`
+process. The `oom_kill` process then terminates memory-hungry processes.
+
+To prevent ballooning, configure VyOS routers in a resource group with
+adequate memory reservations.
