feat(camofox): stack files (PARKED — not deployed, upstream browser bug)

Image camofox-browser:135.0.1-x86_64 builds + serves, but camoufox fails to
launch: "cannot open display: [object Promise]" (upstream un-awaited Promise in
the virtual_display path). HTTP /health ok, browserRunning:false. NOT deployed:
no Caddy route, no Portainer registration, no Hermes wiring. Resume once the
upstream display bug is fixed (re-add Caddy block + register stack).

+# No published image: built on-host as camofox-browser:135.0.1-x86_64 via `make build` in the
+# upstream clone (/storage1/hermes/workspace/clones/camofox-browser). pull_policy: never so

+# Internal-only: published on the edge host-IP (172.20.0.1:9377) so host-side Hermes can reach
+# it directly, and joined to `edge` so Caddy reaches it by container name. Bearer-auth enforced
+# by camofox itself (CAMOFOX_ACCESS_KEY). Image pinned out of Watchtower.
