chore: update files array & build paths

[brionmario]

Purpose

This pull request includes updates to the .gitignore and package.json files to enhance project configuration and build process. The most important changes are:

.gitignore updates:

• Added patterns to ignore various log files, diagnostic reports, runtime data, and cache directories. This helps in keeping the repository clean and prevents unnecessary files from being tracked.

package.json updates:

• Changed the main entry point and types from ./build to ./dist to reflect the new build output directory.
• Updated the files array to include dist instead of build and added LICENSE to the list of files to be included in the package.

Related Issues
