Closes #293

Adds github-actions.workflow.run.delete (Delete workflow run) for completed workflow runs where the user has write permissions (viewItem =~ /run/ && viewItem =~ /rerunnable/), matching the confirmation dialog and remove.svg inline icon pattern used for deleting secrets and variables:

• Prompts with a modal confirmation dialog showing the run number before calling gitHubRepoContext.client.actions.deleteWorkflowRun (src/commands/deleteWorkflowRun.ts, src/commands/deleteWorkflowRunHandler.ts)
• Contributes both an inline action button (group: inline@2 with resources/icons/{dark,light}/remove.svg) and a context menu entry on completed workflow runs, hidden from the Command Palette (package.json)
• Refreshes github-actions.explorer.refresh and github-actions.explorer.current-branch.refresh after deletion, and surfaces API errors via showErrorMessage
• Adds unit tests in src/commands/deleteWorkflowRun.test.ts covering manifest contributions, confirmed deletion + refresh, modal cancellation no-op, and error reporting
