fix(studio): refresh sidebar metadata when switching packages

Make the sidebar package dropdown drive the URL instead of local state.
The $package layout already syncs selectedPackage from the URL param, so
the previous setSelectedPackage-only handler was being immediately reverted
by that effect, which kept AppSidebar.loadMetadata from re-running. Now
selecting a package navigates to /$newPackage; the URL->state effect
updates selectedPackage, which invalidates loadMetadata's dependency and
refreshes the left metadata list for the newly selected package.

   - Updated `content/docs/guides/packages.mdx` and `content/docs/concepts/packages.mdx` to reflect the actual **42 package** inventory and to include `service-package` and `service-tenant`
 
 ### Fixed
+- **Studio left metadata list not refreshing on package switch** — In `apps/studio/src/routes/$package.tsx`, the `AppSidebar` package-switcher's `onSelectPackage` handler only updated local `selectedPackage` state. A URL→state `useEffect` in the same layout then immediately reverted that state back to match the unchanged `$package` route param, so `AppSidebar.loadMetadata` (keyed on `selectedPackage`) never re-ran and the left metadata tree stayed stuck on the previous package. The dropdown now navigates to `/$newPackage`, making the URL the single source of truth; the URL→state effect then updates `selectedPackage` normally and the metadata list refreshes for the new package. (`apps/studio/src/routes/$package.tsx`)
 - **Cross-origin auth tokens stripped in `@objectstack/hono` adapter (follow-up to PR #1178)** — `createHonoApp()` was not exposing `set-auth-token` via `Access-Control-Expose-Headers`, diverging from `plugin-hono-server`'s CORS wiring. On Vercel deployments (where all traffic flows through `createHonoApp()`), the browser stripped the header from every response, preventing the better-auth `bearer()` plugin from delivering rotated session tokens to cross-origin clients. Cross-origin sessions silently broke even after the wildcard fixes in #1177/#1178. The adapter now always includes `set-auth-token` in `exposeHeaders`, merged with any user-supplied values, mirroring the invariant established in commit `151dd19c`. (`packages/adapters/hono/src/index.ts`)
 - **CORS wildcard patterns in `@objectstack/hono` adapter (follow-up to PR #1177)** — `createHonoApp()` was the third CORS code path that still treated wildcard origins (e.g. `https://*.objectui.org`) as literal strings when passing them to Hono's `cors()` middleware. Because `apps/server` routes all non-OPTIONS requests through this adapter on Vercel, the browser would see a successful preflight (handled by the Vercel short-circuit) followed by a POST/GET response with no `Access-Control-Allow-Origin` header, blocking every real request. The adapter now imports `hasWildcardPattern` / `createOriginMatcher` from `@objectstack/plugin-hono-server` and uses the same matcher-function branch as `plugin-hono-server`, so all three Hono-based CORS paths share a single source of truth. (`packages/adapters/hono/src/index.ts`)
 - **CORS wildcard patterns on Vercel deployments** — `CORS_ORIGIN` values containing wildcard patterns (e.g. `https://*.objectui.org,https://*.objectstack.ai,http://localhost:*`) no longer cause browser CORS errors when `apps/server` is deployed to Vercel. The Vercel entrypoint's OPTIONS preflight short-circuit previously matched origins with a literal `Array.includes()`, treating `*` as a plain character and rejecting legitimate subdomains. It now shares the same pattern-matching logic as the Hono plugin's `cors()` middleware via new exports `createOriginMatcher` / `hasWildcardPattern` / `matchOriginPattern` / `normalizeOriginPatterns` from `@objectstack/plugin-hono-server`. (`apps/server/server/index.ts`, `packages/plugins/plugin-hono-server/src/pattern-matcher.ts`)
