Detect VS Code bundled built-in extensions in ai_tools

[juan-fdz-hawa]

Resolves #50705

The ide_plugins collector only scanned the user profile's extensions directory. GitHub Copilot Chat ships bundled inside the application from VS Code 1.130+ and the standalone marketplace extension is deprecated, so an actively-enabled Copilot returned zero rows.

Scan application install directories for bundled extensions, covering both the macOS .app/Contents/Resources/app/extensions layout and the Windows/Linux resources/app/extensions layout. Display names are resolved from package.nls.json, and rows are deduped against the user-profile pass since VS Code gives the profile copy precedence.

Checklist for submitter

If some of the following don't apply, delete the relevant line.

• Changes file added for user-visible changes in changes/, orbit/changes/ or ee/fleetd-chrome/changes.
  See Changes files for more information.

• Input data is properly validated, SELECT * is avoided, SQL injection is prevented (using placeholders for values in statements), JS inline code is prevented especially for url redirects, and untrusted data interpolated into shell scripts/commands is validated against shell metacharacters.

• Timeouts are implemented and retries are limited to avoid infinite loops

• If paths of existing endpoints are modified without backwards compatibility, checked the frontend/CLI for any necessary changes

Testing

• Added/updated automated tests

• Where appropriate, automated tests simulate multiple hosts and test for host isolation (updates to one hosts's records do not affect another)

• QA'd all new/changed functionality manually

For unreleased bug fixes in a release candidate, one of:

• Confirmed that the fix is not expected to adversely impact load test results
• Alerted the release DRI if additional load testing is needed

Database migrations

• Checked schema for all modified table for columns that will auto-update timestamps during migration.
• Confirmed that updating the timestamps is acceptable, and will not cause unwanted side effects.
• Ensured the correct collation is explicitly set for character columns (COLLATE utf8mb4_unicode_ci).

New Fleet configuration settings

• Setting(s) is/are explicitly excluded from GitOps

If you didn't check the box above, follow this checklist for GitOps-enabled settings:

• Verified that the setting is exported via fleetctl generate-gitops
• Verified the setting is documented in a separate PR to the GitOps documentation
• Verified that the setting is cleared on the server if it is not supplied in a YAML file (or that it is documented as being optional)
• Verified that any relevant UI is disabled when GitOps mode is enabled

fleetd/orbit/Fleet Desktop

• Verified compatibility with the latest released version of Fleet (see Must rule)
• If the change applies to only one platform, confirmed that runtime.GOOS is used as needed to isolate changes
• Verified that fleetd runs on macOS, Linux and Windows
• Verified auto-update works from the released version of component to the new version (see tools/tuf/test)

Walkthrough

The VS Code family scanner now detects AI extensions bundled inside supported applications on macOS, Windows, and Linux. It searches platform-specific application layouts, reads extension manifests, resolves localized display names, and preserves profile-extension precedence. Manifest conversion and AI classification are centralized in a helper. Tests cover platform detection, metadata, localization, filtering, duplicate suppression, and temporary-home isolation.
