chore: bump version to 0.4.4

package.json had drifted out of sync with git tags since v0.4.0
(tags were cut without a matching package.json bump); this catches
it up and covers the bookmark links-list feature.

 # PulseNode
 
 A self-hosted infrastructure dashboard: system stats, Docker containers,
-databases, and HTTP/Traefik health, configured entirely through a YAML file
+databases, HTTP checks, and combined docker+API service widgets, configured
-and pushed to the browser live over WebSockets. No database of its own -
+entirely through a YAML file and pushed to the browser live over WebSockets.
-`config.yml` is the source of truth, metrics are ephemeral.
+No database of its own - `config.yml` is the source of truth, metrics are
+ephemeral.
 
 ## Features
 
 - **YAML-configured** widgets and layout, hot-reloaded - edit `config.yml`
   and connected browsers update without a page refresh
 - **Secrets via `.env`**, interpolated into `config.yml` at load time
-  (`${VAR}` / `${VAR:-default}`), never sent to the browser
+  (`${VAR}` / `${VAR:-default}`). Widget fields named `apiToken`/`apiKey`/
+  `password` are stripped before the config ever reaches the browser
+  (`lib/config/public.ts`) - collectors run server-side and use the real
+  values, the client never sees them
 - **Live updates over WebSocket** - each widget subscribes to its own topic;
   the server only serializes results for widgets someone is actually viewing
 - **Widget types**: Docker containers, Postgres/Redis instances, system
-  resources, HTTP health checks, Traefik router status, bookmarks, search
+  resources, HTTP health checks, combined docker+API service widgets
+  (Gitea, Coolify, Immich, n8n, Umami, Headscale, Traefik), bookmarks, search
 - **Optional label-based auto-discovery** - containers carrying
   `traefik.enable=true` can be turned into dashboard widgets automatically;
   manual `config.yml` entries always take precedence
