Fulltext indexes rely on CDC to track changes for asynchronous index
building. Enforce the following CDC constraints during CREATE INDEX:
- CDC TTL must be at least 86400 seconds (24 hours)
- CDC delta mode must be 'full' or postimage must be enabled
Add `has_fulltext_index()` and `check_cdc_options()` so that other
modules can detect fulltext indexes and validate CDC settings:
- include fulltext indexes in `cdc_enabled()` so the CDC log
is auto-created, and validate CDC options in
`on_before_update_column_family()`
- block `ALTER TABLE ... WITH cdc = {'enabled': false}`
when a fulltext index exists on the table
