chore: remove applicationinsights-web-basic override after upstream fix release (fixes #614)

[hanhan761]

Summary

The @microsoft/applicationinsights-web-basic override was pinned to ~3.3.4 as a workaround for @vscode/extension-telemetry issue #244. The upstream fix was released in v1.5.2, so the override is no longer needed.

Changes

• Removed @microsoft/applicationinsights-web-basic: ~3.3.4 from overrides in package.json
• Updated the //overrides comment to remove the applicationinsights mention

Issue

Fixes #614

Verification

• npm install completed successfully — dependencies resolve correctly without the override
• Only package.json changed (2 insertions, 3 deletions)

• Updates read/write paths to record access to support LRU behavior.
• Removes an Application Insights-related dependency override and updates the overrides note.

Thanks for picking this up, @hanhan761! The core change is exactly right and the prerequisites are all met -- extension-telemetry 1.5.2 is out and vscode-azext-utils 4.1.x has already updated its dependency range to pick it up.

We did a small cleanup before merging. The branch had two independent changes bundled together: the override removal (issue #614) and the SchemaStore LRU eviction (issue #604). The LRU work had already landed on main separately, so keeping it here would have created a conflict. We also noticed the package-lock.json was not updated in the PR -- without regenerating it, the nested duplicate AI packages would have stayed in the lockfile and the bundle size improvement would not have been visible.

We force-pushed a single clean commit that covers only issue #614: removes the override from package.json, updates the comment, and includes the regenerated package-lock.json. The lockfile now resolves applicationinsights-web-basic to a single ^3.4.1 entry (was two nested copies), which recovers the expected ~100-120 KB from the VSIX.

One note for future PRs: we noticed the same pattern of bundling unrelated changes in your other open PRs as well -- sorry for not flagging it sooner. Keeping each PR focused on one issue makes reviews much easier, both for confirming the change matches the issue requirements and for isolating any regressions. No worries at all, just something worth keeping in mind going forward.

Everything passes and we will merge this shortly. Great contribution!
