oikos-web: extract the client stack from dtoro/oikos

Phase 1 of the hexagonal-architecture plan (dtoro/oikos plans/2026-08-15-hexagonal-architecture.md). Moves the delivery stack for the control-room UI into its own repo with its own pipeline: - web/ — Svelte 5 SPA, verbatim (vendor/ included) - desktop/ — Wails v3 wrapper, updateURL repointed to dtoro/oikos-web releases - compose/ — Dockerfile + Caddyfile, verbatim (the /wails/* 404 and asset no-fallback quirks are load-bearing) - docker-compose.yml — single web service, same 8091:80 publish, mem/cpu limits, and restart policy as the oikos stack's web service - scripts/deploy.sh — mirrors oikos deploy essentials: CI-green gate, TOCTOU guard, version-tagged oikos-web:v$VERSION, prune to 3 - cmd/webhook + scripts/install-webhook.sh — standalone push-to-deploy receiver on :9798 (env-only secrets, no Infisical dependency) - CI: the web job from oikos's ci.yml + the desktop build/release workflow, path-adjusted Own VERSION (0.33.0) with the same bump-on-main rule; starts above oikos's 0.32.x so the desktop updater sees an upgrade.
