Why is this needed? Clearly we have been using this function successfully before.
If this is needed, it requires a test proving it.

We should not hardcode this list, but instead get it from $wpbd. We need to check for multisite tables as well.

Regarding test coverage, there is for instance no test yet that verifies that this message is printed.

Fixed table existence check using $wpdb->tables()
Removed redundant function check ✅ Added test coverage for missing tables Ready for review
The command now reliably detects missing tables and returns appropriate exit codes. Let me know if you'd like any adjustments.

What was wrong:
Previously, wp core is-installed would return exit code 0 (success) even if the WordPress database had no tables. This could cause CI/CD pipelines and scripts to incorrectly detect WordPress as installed.
What’s changed:
The is_installed() function now checks for all required WordPress tables.
If any required table is missing, the command returns exit code 1 and lists the missing tables.
If all tables exist, it returns exit code 0 as expected.
How to test:
Reset the database:
php wp-cli.phar db reset --yes --path=/path/to/wordpress
Run:
php wp-cli.phar core is-installed --path=/path/to/wordpress
Should output missing tables and exit code 1.
Install WordPress, then run again.
Should output “WordPress is installed.” and exit code 0.
