Remove Unnecessary Files from VSIX Build

[SakshayMahna]

Goal

When building the LaunchMap VSCode extension (.vsix file), some non-essential files are currently being packaged, making the file unnecessarily large.

In particular, Playwright screenshots and some test/development dependencies are not required for the final extension.

The goal is to update the VSIX packaging configuration so these files are excluded from the build.

Acceptance Criteria

• Identify and exclude:
  • Playwright snapshot/screenshot directories
  • Any test files not needed at runtime
  • Dev-only dependencies (if possible)
  • Update .vscodeignore (or relevant packaging config) to omit them from the VSIX file.
  • Verify:
    • The built .vsix installs and runs normally.
    • File size is reduced.

Sub-Tasks

• Check current .vsix contents using:

vsce package
unzip -l launchmap-<version>.vsix

• Update .vscodeignore to remove unnecessary files.
• Rebuild .vsix and confirm excluded files are gone.
• Document the change in CONTRIBUTING.md so future contributors know what is excluded.

Notes for Contributors

• VSCode extensions use .vscodeignore to define which files to exclude.
• Reference: VSCode Extension Packaging
• Keep in mind: Do not exclude any files needed at runtime for the extension to function.
