feat: Phase 1 — extract the client (web SPA + desktop) to dtoro/oikos-web

Problem: the hexagonal refactor churns the backend tree for nine more
phases; the UI delivery stack (web/ SPA, cmd/desktop Wails wrapper,
compose/web image) must move to its own repo first so doc/layout
rewrites land once on a backend-only tree.

Change:
- New repo git.hubris.network/dtoro/oikos-web (v0.33.0): web/, desktop/
  (updateURL repointed to oikos-web releases), compose/, own CI (web +
  desktop jobs), own deploy script (CI-green gate, TOCTOU guard,
  version-tagged images, prune-to-3), own webhook receiver on :9798 +
  launchd unit, own compose project publishing the same 8091:80.
- Cutover executed on mac-mini in order: oikos stack's web service
  stopped+removed, oikos-web project brought up on 8091; outer Caddy
  untouched (targets the published port) — serving + Authentik flow +
  /wails 404 quirk verified post-cutover.
- Stripped from oikos: web/, cmd/desktop/, compose/web/, desktop CI
  workflow, ci.yml web job, Makefile ui/desktop/desktop-package/install
  targets, the compose web service, oikos-web from deploy.sh's fallback
  prune list; wails + go-keyring dropped from go.mod, vendor synced.
- README / CONTRIBUTING / AGENTS.md / .agents dev+operations docs now
  point at the new repo; mbse + mascot design docs carry a path note.

Risk: production SPA serving depends on the new pipeline now; rollback
is versioned-image re-up of the old web service from a pre-split
checkout (port 8091). Desktop builds installed before the split still
check dtoro/oikos releases — one manual reinstall, noted in the
oikos-web release notes.

Verification: go vet, make test (race), make generate-check, golangci
(no new findings; baseline down 400→365); post-cutover curls —
localhost:8091 200, /wails/runtime.js 404, outer Caddy 302 Authentik.

+/**
+ * Answers "does this real domain match the domain in a cookie?". The `domain` is the "current" domain name and the
+ * `cookieDomain` is the "cookie" domain name. Matches according to {@link https://www.rfc-editor.org/rfc/rfc6265.html#section-5.1.3 | RFC6265 - Section 5.1.3},
+ * but it helps to think of it as a "suffix match".
+ *
+ * @remarks
+ * ### 5.1.3.  Domain Matching
+ *
+ * A string domain-matches a given domain string if at least one of the
+ * following conditions hold:
+ *
+ * - The domain string and the string are identical.  (Note that both
+ *     the domain string and the string will have been canonicalized to
+ *     lower case at this point.)
+ *
+ * - All of the following conditions hold:
+ *
+ *     - The domain string is a suffix of the string.
+ *
+ *     - The last character of the string that is not included in the
+ *         domain string is a %x2E (".") character.
+ *
+ *     - The string is a host name (i.e., not an IP address).
+ *
+ * @example
+ * ```
+ * domainMatch('example.com', 'example.com') === true
+ * domainMatch('eXaMpLe.cOm', 'ExAmPlE.CoM') === true
+ * domainMatch('no.ca', 'yes.ca') === false
+ * ```
+ *
+ * @param domain - The domain string to test
+ * @param cookieDomain - The cookie domain string to match against
+ * @param canonicalize - The canonicalize parameter toggles whether the domain parameters get normalized with canonicalDomain or not
+ * @public
