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.

+ESQuery is a library for querying the AST output by Esprima for patterns of syntax using a CSS style selector system. Check out the demo:
+
+[demo](https://estools.github.io/esquery/)
+
+The following selectors are supported:
+* AST node type: `ForStatement`
+* [wildcard](http://dev.w3.org/csswg/selectors4/#universal-selector): `*`
+* [attribute existence](http://dev.w3.org/csswg/selectors4/#attribute-selectors): `[attr]`
+* [attribute value](http://dev.w3.org/csswg/selectors4/#attribute-selectors): `[attr="foo"]` or `[attr=123]`
+* attribute regex: `[attr=/foo.*/]` or (with flags) `[attr=/foo.*/is]`
+* attribute conditions: `[attr!="foo"]`, `[attr>2]`, `[attr<3]`, `[attr>=2]`, or `[attr<=3]`
+* nested attribute: `[attr.level2="foo"]`
+* field: `FunctionDeclaration > Identifier.id`
+* [First](http://dev.w3.org/csswg/selectors4/#the-first-child-pseudo) or [last](http://dev.w3.org/csswg/selectors4/#the-last-child-pseudo) child: `:first-child` or `:last-child`
+* [nth-child](http://dev.w3.org/csswg/selectors4/#the-nth-child-pseudo) (no ax+b support): `:nth-child(2)`
+* [nth-last-child](http://dev.w3.org/csswg/selectors4/#the-nth-last-child-pseudo) (no ax+b support): `:nth-last-child(1)`
+* [descendant](http://dev.w3.org/csswg/selectors4/#descendant-combinators): `ancestor descendant`
+* [child](http://dev.w3.org/csswg/selectors4/#child-combinators): `parent > child`
+* [following sibling](http://dev.w3.org/csswg/selectors4/#general-sibling-combinators): `node ~ sibling`
+* [adjacent sibling](http://dev.w3.org/csswg/selectors4/#adjacent-sibling-combinators): `node + adjacent`
+* [negation](http://dev.w3.org/csswg/selectors4/#negation-pseudo): `:not(ForStatement)`
+* [has](https://drafts.csswg.org/selectors-4/#has-pseudo): `:has(ForStatement)`, `:has(> ForStatement)`
+* [matches-any](http://dev.w3.org/csswg/selectors4/#matches): `:is([attr] > :first-child, :last-child)`
+* [subject indicator](http://dev.w3.org/csswg/selectors4/#subject): `!IfStatement > [name="foo"]`
+* class of AST node: `:statement`, `:expression`, `:declaration`, `:function`, or `:pattern`
