Query Table 0.4.2

Consumers that use case-sensitive keys in text arrays currently match Bug and bug as the same value. Add opt-in filter.arrayCaseSensitive so local queries, metrics, PostgreSQL membership, and generated schemas preserve exact keys; existing consumers retain case-insensitive behavior.

Includes regression coverage for positive and negated membership, empty arrays, OR groups, pagination, metrics, schema loading, and code generation. Bumps all packages to 0.4.2 for consumption by TL1.
