Introduce `fulltext_index`, a new `custom_index` subclass for full-text search (FTS). The index validates that the target column is a text type (text, varchar, or ascii) and supports two WITH OPTIONS keys: - 'analyzer': one of standard, english, german, french, spanish, italian, portuguese, russian, chinese, japanese, korean, simple, whitespace - 'positions': boolean controlling whether term positions are stored `view_should_exist()` returns false — no backing materialized view is created, matching the CDC-backed pattern used by `vector_index`. Fixes: SCYLLADB-1517
