Correct the "Welcome" heading typo and reword "Index Suggestions"
in the feature list. The intro now lists all six exportable SQL
dialects (adding Oracle and SQL Server) so it matches the
Supported Databases section. Add the port 3000 dev-server URL to
the local setup instructions, and switch the Docker Compose
commands in README and DOCKER.md from the deprecated V1
"docker-compose" to the current V2 "docker compose" syntax.
