Pull request overview

Adds a clickable "Configure Environment Variables" diagnostic code link in the Problems view that opens the workspace settings filtered to cmsis-csolution.environmentVariables, addressing the request in issue #251 to make environment-variable diagnostics actionable.

Changes:

• Introduces a new EnvironmentVariablesSettingsCommand registering cmsis-csolution.openEnvironmentVariablesSettings, activated in desktop/extension.ts.
• Extends ProblemDiagnosticActionResolver to detect "missing/non-existent" environment variable diagnostic messages and emit a code link targeting the new command.
• Adds unit tests covering the new resolver branch, the command registration/behavior, and the end-to-end diagnostic wiring in SolutionProblems.

It looks good to me.
I would suggest to add this link also when it concerns this "west" error:

Add a link to settings when west executable is not found.
