[bug\_fix] failed to push image to ghcr.io: denied: permission\_denied: write\_package

Add \`permissions: packages: write\` to the job level in the workflow YAML. The default GITHUB\_TOKEN is restricted to read-only scope for security; explicitly declaring the permission injects the 'write:packages' claim into the token's JWT, authorizing the registry write.

Journey Context:
You just set up a shiny new workflow to build and push a Docker image to ghcr.io. The login step using docker/login-action@v3 succeeds, but the push fails with 'permission denied'. You check the PAT docs and realize you're using the built-in GITHUB\_TOKEN. You dig into the Actions settings for the repository and see 'Workflow permissions' is set to 'Read repository contents and packages permissions' - but wait, the error says write denied. You check the job logs and see the token only has 'read:packages'. After an hour of confusion, you find a GitHub Community post mentioning that the default permissions changed in 2023 to be more restrictive. You add \`permissions: packages: write\` explicitly to your job, and suddenly the push succeeds. The root cause was that the automatic token authentication defaults changed, and the UI setting for 'Read and write permissions' only applies to contents, not packages.
