Google Tag Manager environment support, plus a nav-highlight fix and release/deploy CI fixes.

• add support for Google Tag Manager environments (70a3fac, #451)

  // docula.config.ts — target a specific GTM environment (staging, QA, …)
  export const options: Partial<DoculaOptions> = {
    googleTagManager: 'GTM-XXXXXX',
    googleTagManagerAuth: 'abc123', // → gtm_auth
    googleTagManagerEnv: 'env-3',   // → gtm_preview
  };
  

Client-side search (⌘K), SSRF hardening, SEA binary fixes, and a dependency refresh.

• add built-in client-side search (⌘K) to the modern template (a3d3c1c, #445)

  // docula.config.json — search is on by default for the modern template;
  // build emits search-index.json and renders the ⌘K / Ctrl-K modal.
  { "enableSearch": true }   // set to false to disable
  

• search: robust HTML stripping and Enter-key race in client search (5d4392c, #445)

Node 20 → 22 minimum, pnpm 11 supply-chain hardening, AI SDK + tooling refresh, and favicon auto-generation.

• Drop Node 20 support; minimum engines are now ^22.18.0 || >=24.0.0 (3420df2, #416) Migration: upgrade to Node 22 LTS or Node 24+. pnpm is now managed via corepack; run corepack enable and pnpm 11.1.3 is pinned via packageManager.
