fix: missing docker compose template files

[stevensJourney]

closes #19

Users have reported the following error when running powersync docker configure

    Error: ENOENT: no such file or directory, open '/home/lcmch/.npm/_npx/0be151bc818c02b
    f/node_modules/@powersync/cli-plugin-docker/dist/templates/main-compose.yaml'
    Code: ENOENT

The docker plugin package has a script which should copy template files to the dist folder.

It seems like the @powersync/cli-plugin-docker package's build script was somehow deleted - perhaps due to a merge conflict resolution.

This re-adds the script which resolves the issue. Tested by doing a clean build then using docker commands.

A dev release was also tested.

❯ npx powersync@0.0.0-dev-20260305082615 docker configure
✔ Select a database module for a replication source. Use external to configure an existing database. postgres
✔ Select a storage module for PowerSync bucket metadata. Use external to configure an existing database. postgres
Note: the Postgres database template is incomplete.
Update docker/modules/database-postgres/init-scripts/ with your schema (tables and publication) before deploying.
Init scripts run only when the DB volume is empty. If you see "Publication powersync does not exist", run: powersync docker stop --remove --remove-volumes then powersync docker reset again.

Configured /Users/stevenontong/Documents/platform_code/powersync/new-cli/playground/powersync/docker
  - docker-compose.yaml (includes modules, adds PowerSync service)
  - .env
  - Merged config into service.yaml
  - cli.yaml (plugins.docker.project_name: powersync_playground)

Next: run "powersync docker start" to start the stack.

Side addition: this adds a LICENSE file to the repo root.

Solid.
