feat(website): update home page to showcase CherryPick DI documentation

- Replaced the main action button text with 'Explore CherryPick Documentation 🍒' instead of 'Docusaurus Tutorial'.
- Updated the button link to target /docs/intro (main docs entry point).
- Changed <Layout> props:
  - Page title now uses project title only (siteConfig.title)
  - Added a CherryPick-related site description for better SEO and context.
- The homepage is now tailored to reflect CherryPick's purpose as a Dart & Flutter DI library instead of Docusaurus boilerplate.

+# Logging
+
+CherryPick lets you log all dependency injection (DI) events and errors using a flexible observer mechanism.
+
+## Custom Observers
+You can pass any implementation of `CherryPickObserver` to your root scope or any sub-scope.
+This allows centralized and extensible logging, which you can direct to print, files, visualization frameworks, external loggers, or systems like [Talker](https://pub.dev/packages/talker).
+
+### Example: Printing All Events
+
+```dart
+import 'package:cherrypick/cherrypick.dart';
+
+void main() {
+  // Use the built-in PrintCherryPickObserver for console logs
+  final observer = PrintCherryPickObserver();
+  final scope = CherryPick.openRootScope(observer: observer);
+  // All DI actions and errors will now be printed!
+}
+```
+
+### Example: Advanced Logging with Talker
+
+For richer logging, analytics, or UI overlays, use an advanced observer such as [talker_cherrypick_logger](../talker_cherrypick_logger):
+
+```dart
+import 'package:cherrypick/cherrypick.dart';
+import 'package:talker/talker.dart';
+import 'package:talker_cherrypick_logger/talker_cherrypick_logger.dart';
+
+void main() {
+  final talker = Talker();
+  final observer = TalkerCherryPickObserver(talker);
+  CherryPick.openRootScope(observer: observer);
+  // All container events go to the Talker log system!
+}
+```
+
+## Default Behavior
+- By default, logging is silent (`SilentCherryPickObserver`) for production, with no output unless you supply an observer.
+- You can configure observers **per scope** for isolated, test-specific, or feature-specific logging.
+
+## Observer Capabilities
+Events you can observe and log:
+- Dependency registration
+- Instance requests, creations, disposals
+- Module installs/removals
+- Scope opening/closing
+- Cache hits/misses
+- Cycle detection
+- Diagnostics, warnings, errors
+
+Just implement or extend `CherryPickObserver` and direct messages anywhere you want!
+
+## When to Use
+- Enable verbose logging and debugging in development or test builds.
+- Route logs to your main log system or analytics.
+- Hook into DI lifecycle for profiling or monitoring.
