feat: surface extension and analyzer versions for issue reports

[Arthurvdv]

Problem

When users create an issue there's confusion about which version they are on: the VS Code extension has its own version, but most of the time the version of the downloaded ALCops.Analyzers NuGet package is what actually matters. That version is recorded in .alcops-manifest.json but surfaced nowhere persistent — the status bar shows only a count, there is no output channel, and version strings appear only in 5-second auto-dismissing toasts.

Solution

Follows the pattern used by extensions with separately-versioned downloaded components (rust-analyzer, Python's language server, CMake Tools, C/C++):

• New command ALCops: Copy Version Information — copies a ready-to-paste diagnostics block to the clipboard:

  ALCops extension: 1.4.1
  ALCops.Analyzers: 0.9.2 (channel: stable)
  AL Language extension: 18.0.123456
  VS Code: 1.103.1
  OS: win32 x64 (Windows_NT 10.0.26200)
  Analyzers path: <path>
  Downloaded at: <timestamp>
  Target framework: net8.0
  

• New "ALCops" output channel (LogOutputChannel) — version banner on activation and after every install/update; all existing console.* logging routed through it via a new src/logger.ts facade (console fallback keeps pure-Node modules importable in vitest)
• Status bar tooltip now shows extension, analyzers (with channel), and AL Language versions as markdown; the ALCops: <n> text and click-to-select behavior are unchanged. Version info is cached and invalidated only on install or alcops.versionChannel change

src/version-info.ts is the single source of truth: gatherVersionInfo() plus pure formatters shared by the tooltip, clipboard block, and log banners. Handles AL extension missing, manifest missing/corrupt, and the pending-update 'unknown' placeholder as "not installed".

Notification wording and .github/ISSUE_TEMPLATE are deliberately untouched.

Testing

• 49/49 unit tests pass (11 new in tests/version-info.test.ts), lint clean, typecheck clean, bundle builds
• Manually verified in the extension host: output channel banner, tooltip, copy command (including "not installed" state), install logging, and live tooltip refresh on channel change
