feat: implement complete plugin store repository synchronization system

• Fix repository sync implementation in admin API (was TODO placeholder)
- Add full fetch/parse logic for repository.json and plugin index -
Implement robot matching by name/manufacturer patterns - Handle plugin
creation/updates with proper error handling - Add comprehensive
TypeScript typing throughout

• Fix plugin store installation state detection - Add getStudyPlugins
API integration to check installed plugins - Update PluginCard component
with isInstalled prop and correct button states - Fix repository name
display using metadata.repositoryId mapping - Show "Installed"
(disabled) vs "Install" (enabled) based on actual state

• Resolve admin access and authentication issues - Add missing
administrator role to user system roles table - Fix admin route access
for repository management - Enable repository sync functionality in
admin dashboard

• Add repository metadata integration - Update plugin records with
proper repositoryId references - Add metadata field to
robots.plugins.list API response - Enable repository name display for
all plugins from metadata

• Fix TypeScript compliance across plugin system - Replace unsafe 'any'
types with proper interfaces - Add type definitions for repository and
plugin data structures - Use nullish coalescing operators for safer null
handling - Remove unnecessary type assertions

• Integrate live repository at https://repo.hristudio.com - Successfully
loads 3 robot plugins (TurtleBot3 Burger/Waffle, NAO) - Complete ROS2
action definitions with parameter schemas - Trust level categorization
(official, verified, community) - Platform and documentation metadata
preservation

• Update documentation and development workflow - Document plugin
repository system in work_in_progress.md - Update quick-reference.md
with repository sync examples - Add plugin installation and management
guidance - Remove problematic test script with TypeScript errors

BREAKING CHANGE: Plugin store now requires repository sync for robot
plugins. Run repository sync in admin dashboard after deployment to
populate plugin store.

Closes: Plugin store repository integration Resolves: Installation state
detection and repository name display Fixes: Admin authentication and
TypeScript compliance issues

 ### **Plugin System Design**
 
+**Unified Plugin Architecture**: HRIStudio uses a consistent plugin system for both core blocks and robot actions, providing complete architectural consistency.
+
+#### **Core Blocks System**
+
+**Repository Structure**:
+```
+public/hristudio-core/
+├── repository.json           # Repository metadata
+├── plugins/
+│   ├── index.json           # Plugin index (26 total blocks)
+│   ├── events.json          # Event trigger blocks (4 blocks)
+│   ├── wizard-actions.json  # Wizard action blocks (6 blocks)
+│   ├── control-flow.json    # Control flow blocks (8 blocks)
+│   └── observation.json     # Observation blocks (8 blocks)
+└── assets/                  # Repository assets
+```
+
+**Block Loading Architecture**:
+```typescript
+class BlockRegistry {
+  async loadCoreBlocks() {
+    // Fetch from /hristudio-core/plugins/*.json
+    // Parse and validate JSON structures
+    // Convert to PluginBlockDefinition format
+    // Register with unified block system
+    // Fallback to minimal blocks if loading fails
+  }
+}
+```
+
+**Core Block Categories**:
+- **Events (4)**: `when_trial_starts`, `when_participant_speaks`, `when_timer_expires`, `when_key_pressed`
+- **Wizard Actions (6)**: `wizard_say`, `wizard_gesture`, `wizard_show_object`, `wizard_record_note`, `wizard_wait_for_response`, `wizard_rate_interaction`
+- **Control Flow (8)**: `wait`, `repeat`, `if_condition`, `parallel`, `sequence`, `random_choice`, `try_catch`, `break`
+- **Observation (8)**: `observe_behavior`, `measure_response_time`, `count_events`, `record_audio`, `capture_video`, `log_event`, `survey_question`, `physiological_measure`
+
+#### **Robot Plugin Interface**
+
 **Plugin Interface**:
 ```typescript
 interface RobotPlugin {
