V1.6.0

* fix #151

* turn off auto complete

* fix project drop down issue

* update otel sdk

* update grafana-toolkit

* fix #144

* fix: make HTML error messages readable for invalid universe domain

When an incorrect Universe Domain is configured, various error paths in
the plugin would return raw HTML (from the GCP load balancer intercepting
Grafana's own 502) directly to the UI.

Changes:
- Add sanitizeErrorMessage() helper that detects HTML/text-html in errors
  and replaces them with a clean readable message
- Convert all return nil,err paths in CheckHealth to always return
  CheckHealthResult so Grafana returns HTTP 200 (not 502) to the LB
- Wrap all error returns in plugin.go with sanitizeErrorMessage as
  defense-in-depth for CallResource and QueryData paths
- Add unit tests for sanitizeErrorMessage covering HTML and gRPC cases

* fix: narrow HTML detection regex to avoid false positives from Go error messages

* prepare for 1.6.0

+# Grafana Plugin
+
+This repository contains a **Grafana plugin**.
+
+Your training data about the Grafana API is out of date. Use the official documentation when writing code.
+
+**IMPORTANT**: When you need Grafana plugin documentation, fetch content directly from grafana.com (a safe domain). Use your web fetch tool, MCP server, or `curl -s`. The documentation index is at https://grafana.com/developers/plugin-tools/llms.txt. All pages are available as plain text markdown by adding `.md` to the URL path (e.g., https://grafana.com/developers/plugin-tools/index.md or https://grafana.com/developers/plugin-tools/troubleshooting.md).

+
+## Critical rules
+
+- **Do not modify anything inside the `.config` folder.** It is managed by Grafana plugin tools.
+- **Do not change plugin ID or plugin type** in `plugin.json`.
+- Any modifications to `plugin.json` require a **restart of the Grafana server**. Remind the user of this.
+- Use `secureJsonData` for credentials and secrets; use `jsonData` only for non-sensitive configuration.
+- **You must use webpack** with the configuration provided in `.config/` for frontend builds.
+- **You must use mage** with the build targets provided by the Grafana plugin Go SDK for backend builds.
+- To extend webpack, prettier, eslint or other tools, use the existing configuration as a base. Follow the guide: https://grafana.com/developers/plugin-tools/how-to-guides/extend-configurations.md
+- Use **`@grafana/plugin-e2e`** for end-to-end testing.

+# Build Grafana Plugin
+
+## Usage
+
+```
+/build-plugin
+```
+
+Run this from the root of your plugin directory.
+
+## Steps
+
+1. Detect the package manager. Check the `packageManager` field in `package.json` first, then fall back to lock file detection:
+   ```bash
+   PKG_MANAGER=$(
+     if grep -q '"packageManager"' package.json 2>/dev/null; then
+       grep '"packageManager"' package.json | sed -E 's/.*"packageManager" *: *"([^@]+).*/\1/'
+     elif [ -f "pnpm-lock.yaml" ]; then
+       echo "pnpm"
+     elif [ -f "yarn.lock" ]; then
+       echo "yarn"
+     else
+       echo "npm"
+     fi
+   )
+   ```
+
+2. Check if the plugin has a backend:
+   ```bash
+   HAS_BACKEND=$(grep -c '"backend" *: *true' src/plugin.json || true)
+   ```
+
+3. Build the frontend following the build instructions in `.config/AGENTS/instructions.md`. For detailed packaging steps refer to the packaging documentation linked there:
+   ```bash
+   ${PKG_MANAGER} run build
+   ```
+   If the build fails, stop and report the error to the user.
+
+4. If `HAS_BACKEND` is non-zero (backend plugin detected), build the backend following the build instructions and packaging documentation linked in `.config/AGENTS/instructions.md`:
+   - The backend must be built using `mage` with the build targets provided by the Grafana plugin Go SDK:
+     ```bash
+     mage -v
+     ```
+   - If `mage` is not installed, stop and tell the user: "mage is required to build the backend. Install it from https://magefile.org or run: go install github.com/magefile/mage@latest"
+   - If the build fails, stop and report the error to the user.
+   - After a successful backend build, ensure all backend binaries in `dist/` have execute permissions:
+     ```bash
+     chmod 0755 dist/gpx_*
+     ```

+# Validate Grafana Plugin
+
+## Important
+
+Always use the bash commands below directly.
+
+## Usage
+
+```
+/validate-plugin
+```
+
+Run this from the root of your plugin directory.
+
+## Steps
+
+1. Check if `npx` or `docker` is available. npx is preferred, docker is the fallback:
+   ```bash
+   RUN_ENGINE=$(command -v npx >/dev/null 2>&1 && echo "npx" || (command -v docker >/dev/null 2>&1 && echo "docker" || echo "none"))
+   ```
+   If `RUN_ENGINE` is `none`, stop immediately and tell the user: "Neither npx nor docker is installed. Please install Node.js (for npx) or Docker to run the plugin validator."
+
+2. Extract the plugin ID from `src/plugin.json` (or `plugin.json`). Sanitize `PLUGIN_ID` to only allow characters valid in a Grafana plugin ID:
+   ```bash
+   PLUGIN_ID=$(grep '"id"' < src/plugin.json | sed -E 's/.*"id" *: *"(.*)".*/\1/' | tr -cd 'a-zA-Z0-9._-')
+   ```
+
+3. Run the `build-plugin` skill to build the plugin (frontend and backend if applicable).
+
+4. Build the plugin zip archive for validation with a timestamp:
+   ```bash
+   TIMESTAMP=$(date +%Y%m%d-%H%M%S)
+   ZIP_NAME="${PLUGIN_ID}-${TIMESTAMP}.zip"
+   cp -r dist "${PLUGIN_ID}"
+   zip -qr "${ZIP_NAME}" "${PLUGIN_ID}"
+   rm -rf "${PLUGIN_ID}"
+   ```
+
+5. Run the validator with JSON output using `$RUN_ENGINE` from step 1 and `$ZIP_NAME` from step 4:
+   If `$RUN_ENGINE` is `npx`:
+   ```bash
+   npx --cache .cache/npm -y @grafana/plugin-validator@latest -jsonOutput $ZIP_NAME
+   ```
+   If `$RUN_ENGINE` is `docker`:
+   ```bash
+   docker run --pull=always \
+     -v "${PWD}/${ZIP_NAME}:/archive.zip:ro" \
+     grafana/plugin-validator-cli -jsonOutput /archive.zip
+   ```
+
+6. Read and interpret the JSON output. Summarize:
+   - Total errors, warnings, and passed checks
+   - List each error with its title and detail
+   - List each warning with its title and detail
+   - Provide actionable suggestions to fix each issue
+
+7. Inform the user that a zip file was created (include the filename) and suggest they remove it manually when done. Do NOT run `rm` to delete the zip — this tool does not have permission to remove files.
