feat: improve Zabbix multi-version compatibility and introduce local development environment

This update enhances compatibility across multiple Zabbix versions and introduces tools for easier local development and testing.

Key improvements and verified version support:
- Verified Zabbix version support: 6.2, 6.4, 7.0, and 7.4.
- Version-specific feature handling:
  - `history.push` is enabled only for Zabbix 7.0+; older versions skip it with a clear error or notice.
  - Conditional JSON-RPC authentication: the `auth` field is automatically added to the request body for versions older than 6.4.
  - Implemented static Zabbix version caching in the datasource to minimize redundant API calls.
- Query optimization refinements:
  - Added mapping for implied fields (e.g., `state` -> `items`, `deviceType` -> `tags`).
  - Automatically prune unnecessary Zabbix parameters (like `selectItems` or `selectTags`) when not requested.
- Local development environment:
  - Added a new `zabbix-local` Docker Compose profile that includes PostgreSQL, Zabbix Server, and Zabbix Web.
  - Supports testing different versions by passing the `ZABBIX_VERSION` environment variable (e.g., 6.2, 6.4, 7.0, 7.4).
  - Provided a sample environment file at `samples/zabbix-local.env`.
- Documentation and Roadmap:
  - Updated README with a comprehensive version compatibility matrix and local environment instructions.
  - Created a new guide: `docs/howtos/local_development.md`.
  - Updated maintenance guides and added "Local Development Environment" as an achieved milestone in the roadmap.
- Test suite enhancements:
  - Improved Smoketest and RegressionTest executors with more reliable resource cleanup and error reporting.
  - Made tests version-aware to prevent failures on older Zabbix instances.

BREAKING CHANGE: Dropped Zabbix 6.0 specific workarounds; the minimum supported version is now 6.2.

 ### 🔧 Zabbix Version Compatibility
 
-This API is designed to work with Zabbix 7.4, which is the version it runs productively with. While it may work with earlier versions (like 6.0+), 7.4 is the officially supported and tested version.
+This API is officially supported and productively used with **Zabbix 7.0 (LTS)**, **7.4**, and newer. It maintains compatibility with **Zabbix 6.4** and **6.2**, with the following version-specific behaviors:
+
+- **Zabbix 7.0+ (including 7.4)**:
+    - Full feature support.
+    - **History Push**: Uses the native `history.push` API for efficient data ingestion.
+- **Zabbix 6.4**:
+    - **History Push**: Not supported (requires Zabbix 7.0+). The `pushHistory` mutation returns a clear error.
+    - **Group Propagation**: Fully supported via the `hostgroup.propagate` API.
+    - **UUIDs**: Fully supported for both Host Groups and Template Groups.
+- **Zabbix 6.2**:
+    - **History Push**: Not supported.
+    - **Authentication**: Fully supported. The API automatically falls back to using the `auth` field in JSON-RPC request bodies since Bearer token headers were only introduced in 6.4.
+
+#### ⚠️ Dropped Support for Zabbix 6.0
+Support for Zabbix 6.0 (LTS) has been discontinued due to the excessive complexity of maintaining backward compatibility with its legacy API structure. The high amount of differences between 6.0 and 6.2 would have required several intrusive fallbacks:
+- **API Methods**: A translation layer to redirect `templategroup.*` calls to `hostgroup.*` methods, as these entities were not yet separated.
+- **Permission Management**: Manual recursive expansion of group rights during import because `hostgroup.propagate` was unavailable.
+- **Entity Matching**: Unreliable name-based fallback for host groups due to the lack of UUID support in the 6.0 API.
+- **JSON-RPC**: Complexity in restoring the `auth` field in request bodies for versions lacking modern Bearer token header support.
+
+By requiring **Zabbix 6.2+**, the API leverages native modern features, ensuring higher reliability and a more maintainable codebase.

+# 💻 Local Development Environment
+
+This guide provides detailed instructions on how to set up a fully isolated local development environment for the Zabbix GraphQL API using Docker Compose.
+
+## 🚀 Overview
+The project includes a Docker Compose profile that launches a complete Zabbix stack alongside the GraphQL API and MCP server. This allows you to develop and test features against different Zabbix versions without needing an external Zabbix installation.
+
+### Included Services
+- **`zabbix-graphql-api`**: The main GraphQL server.
+- **`apollo-mcp-server`**: The Model Context Protocol server for AI integration.
+- **`postgres-server`**: PostgreSQL 16 database for Zabbix.
+- **`zabbix-server`**: Zabbix Server (PostgreSQL version).
+- **`zabbix-web`**: Zabbix Web interface (Nginx/PostgreSQL).
+
+## 🛠️ Step-by-Step Setup
+
+### 1. Start the Environment
+Use the `zabbix-local` profile to start all services. You can optionally specify the Zabbix version using the `ZABBIX_VERSION` environment variable.
+
+```bash
+# Start the latest 7.0 (default)
+docker compose --profile zabbix-local up -d
+
+# Start with a specific Zabbix version (e.g. 6.4)
+ZABBIX_VERSION=alpine-6.4-latest docker compose --profile zabbix-local up -d
+```
+
+### 2. Configure Zabbix
+Once the containers are running, you need to perform a minimal setup in the Zabbix UI:
+
+1. Open `http://localhost:8080` in your browser.
+2. Log in with the default credentials:
+   - **User**: `Admin`
+   - **Password**: `zabbix`
+3. Navigate to **Administration** > **Users** > **API tokens**.
+4. Create a new token for the `Admin` user (or a dedicated service user) and copy it.
+5. **Create Base Host Group**: The API requires a base host group to exist for importing devices.
+   - Navigate to **Configuration** > **Host groups** (or **Data collection** > **Host groups** in Zabbix 7.0).
+   - Create a host group named `Roadwork` (or the value of `ZABBIX_EDGE_DEVICE_BASE_GROUP` in your `.env`).
+   - **Note**: If your base group is nested (e.g., `Roadwork/Devices`), ensure the full path exists. Zabbix does not automatically create parent groups when creating child groups via the API.
+
+### 3. Connect the API
+To connect the GraphQL API to your local Zabbix instance, update your `.env` file with the following values (referenced in `samples/zabbix-local.env`):
+
+```env
+# Internal Docker network URL
+ZABBIX_BASE_URL=http://zabbix-web:8080/
+
+# The token you created in Step 2
+ZABBIX_PRIVILEGE_ESCALATION_TOKEN=your-newly-created-token
+```
+
+### 4. Restart the API
+Apply the configuration by restarting the API container:
+
+```bash
+docker compose restart zabbix-graphql-api
+```
+
+## ✅ Verification
+You can verify the setup by running a simple query against the local API:
+
+```bash
+curl -X POST -H "Content-Type: application/json" \
+  -d '{"query": "{ apiVersion zabbixVersion }"}' \
+  http://localhost:4001/
+```
+
+The `zabbixVersion` should match the version you specified in `ZABBIX_VERSION`.
+
+## 💡 Advanced Usage
+
+### Data Persistence
+Zabbix data is stored in a named Docker volume called `zbx_db_data`. This ensures that your configuration, templates, and hosts are preserved even if you stop or remove the containers.
+
+To perform a clean reset of the environment:
+```bash
+docker compose --profile zabbix-local down -v
+```
+
+### Testing Multiple Versions
+The local environment is perfect for testing the API's version-specific logic (e.g. `history.push` vs `zabbix_sender`). Simply change the `ZABBIX_VERSION` variable and restart the stack.
+
+Supported tags can be found on the [Zabbix Docker Hub](https://hub.docker.com/u/zabbix).

+#### Local Development Setup
+For running integration tests against a real Zabbix instance, it is recommended to use the [Local Development Environment](./local_development.md). This setup allows you to test the API against specific Zabbix versions (e.g. 6.4, 7.0) in an isolated way.
