Subject: [PATCH 1/3] feat: add toolingcompliance analyzer to detect deviation
 from Grafana plugin tooling

This adds a new analyzer that checks if a plugin's source code uses Grafana's
standard plugin tooling (create-plugin). The analyzer checks for:

- Presence of .config directory in source code
- @grafana/create-plugin or related tooling packages in package.json devDependencies

For new plugins, violations are reported as errors. For already published
plugins, they are reduced to warnings to allow for gradual migration.

Closes #507

Subject: [PATCH 2/3] feat: enhance toolingcompliance analyzer with
 comprehensive checks

Extended the toolingcompliance analyzer to include:
- Check for webpack.config.ts extending from .config/webpack
- Check for tsconfig.json extending from .config/tsconfig.json
- Check for standard package.json scripts (dev, build, test, lint)
- Added ToolingDeviationScore to quantify deviation level

Added new test cases covering:
- Fully compliant plugins
- Custom webpack configs that don't extend .config
- Missing standard scripts
- Various edge cases

Closes #507

+You will analyze changes in this Grafana plugin to detect breaking changes and verify SemVer compliance. Use `git diff` to see the diff and `git show` to see full files in a specific commit.
+
+Analyze the changes between the versions focusing on:
+1. Breaking changes (API changes, removed functionality, behavioral changes that could break existing users)
+2. New features (new functionality, new APIs, new options)
+3. Bug fixes (corrections to existing functionality)
+
+## Definitions for Grafana Plugins
+
+### Breaking Changes (require MAJOR version bump)
+- Removed or renamed exported functions, components, or types
+- Changed function signatures (parameters, return types)
+- Removed configuration options
+- Changed default behavior in ways that could break existing setups
+- Removed support for previously supported data formats
+- Changed plugin.json schema in incompatible ways (removed fields, changed types)
+- Removed panel options or changed their structure
+
+### New Features (require MINOR version bump)
+- Added new exported functions, components, or types
+- Added new configuration options
+- Added new panel features or visualization options
+- Added support for new data sources or formats
+- Added new query capabilities
+
+### Bug Fixes (require PATCH version bump)
+- Fixed incorrect behavior
+- Fixed edge cases
+- Performance improvements
+- Documentation updates
+- Dependency updates (non-breaking)
+
+New version: {{.NewVersion}} introduced in commit: {{.NewCommit}}
+Current version: {{.CurrentVersion}} introduced in commit: {{.CurrentCommit}}
+
+Analyze the changes and write your analysis to a JSON file "replies.json" with this format:
+
+{
+  "has_breaking_changes": true|false,
+  "has_new_features": true|false,
+  "has_bug_fixes": true|false,
+  "breaking_changes_list": ["description of breaking change 1", "description of breaking change 2"],
+  "new_features_list": ["description of new feature 1", "description of new feature 2"],
+  "bug_fixes_list": ["description of bug fix 1", "description of bug fix 2"],
+  "recommended_version_bump": "major|minor|patch",
+  "explanation": "Brief explanation of why this version bump is recommended based on the changes"
+}
+
+Use jq to validate replies.json is valid JSON, fix any issues if necessary.
+
+Once you are finished say "I finished the SemVer analysis"

Subject: [PATCH 3/3] fix: remove skipped message from semvercheck and
 regenerate README

- Removed the 'skipped' message from semvercheck analyzer when blocking
  analyzers have errors to avoid changing expected integration test output
- Regenerated README.md to include new analyzers in the table
