Remove dev-dist from git tracking

Remove dev-dist/ directory from version control while preserving files locally.
This directory contains build artifacts that should not be committed to the
repository.

Changes:
- Remove dev-dist/registerSW.js from git tracking
- Remove dev-dist/sw.js from git tracking
- Remove dev-dist/sw.js.map from git tracking
- Remove dev-dist/workbox-54d0af47.js from git tracking
- Remove dev-dist/workbox-54d0af47.js.map from git tracking

The dev-dist/ directory is already properly listed in .gitignore and will
be ignored going forward. Build artifacts remain available locally for
development use.
