Revert zodan.sql to the stricter lolor check.

[ibrarahmad]

add_node() and health_check() accept a destination that already has the lolor extension as long as its tables are empty. Go back to rejecting any lolor schema on the destination, and stop excluding lolor from the structure dump and the user table pre-check.

📝 Walkthrough

Walkthrough

The SQL update changes lolor handling in subscription schema detection, prerequisite validation, and health checks. Existing lolor tables are included in skipped schemas and counted by database-emptiness checks.

Changes

lolor validation flow

Layer / File(s)	Summary
Subscription schema detection samples/Z0DAN/zodan.sql	spock.create_sub now includes the lolor schema when it builds skip_schema_list.
Prerequisite and health checks samples/Z0DAN/zodan.sql	spock.verify_node_prerequisites and spock.health_check now fail when the lolor schema contains tables. Their user-table checks also include lolor. Removed lolor state variables and replication checks no longer participate in these validations.

Poem

A rabbit checks the lolor gate

Tables now reveal their state
Schemas skip the copied track
Empty checks count what comes back
Clean nodes hop through validation straight

Merge Risk: 🟡 Moderate · up to 57c26

The change is not merge-ready because destinations with an empty lolor schema can still be accepted, and the existing integration test is incompatible with the intended rejection behavior. Update the checks and test expectations before merging.

In `@samples/Z0DAN/zodan.sql`:
- Around line 1506-1507: Update both destination validation checks around the
`remotesql`/`dblink` calls to query schema existence via `pg_namespace` or
`information_schema.schemata` for `lolor`, rather than counting rows in
`pg_tables`; preserve the prerequisite check before `skip_schema_list` excludes
that schema.
- Around line 1509-1511: Update the lolor add-node integration test around its
extension setup and add_node assertion to expect rejection when an installed but
empty lolor extension remains; replace expectations for the removed pre-existing
large-object messages with the current health-check error text, including the
corresponding assertion near the second referenced block.
