chore: add commit hooks and prepare script

- adds a pre-commit hook that runs `eslint --fix` on any JS file on the stage
- adds a commit message check that verifies the commit message is in conventional commits format
- adds `husky install` to workspace root `postinstall` script, to be run via `allow-scripts`
- adds a `prepare` lifecycle script which runs the `rebuild` script
- remove `preversion` script
