add materialized column support

[DatGuyJonathan]

Note

Adds end-to-end support for ClickHouse MATERIALIZED columns across schema, DDL, parsing/diffing, codegen (TS/Python), validation, tests, and docs.

• Core/Infra:
  • Add materialized to Column/ClickHouseColumn models, proto (infrastructure_map.proto), JSON/proto (de)serialization, and equivalence/diff logic.
  • Enforce mutual exclusivity with default and forbid primary keys when materialized is set.
• ClickHouse DDL/Mapper:
  • Generate MATERIALIZED in CREATE TABLE and ALTER TABLE ... MODIFY/ADD COLUMN; support REMOVE MATERIALIZED paths.
  • Parse system.columns to capture MATERIALIZED default_type and expressions.
• Codegen:
  • TypeScript: introduce ClickHouseMaterialized type, handle annotation in converters, import/export, and emit correct type tags with TTL/Codec ordering.
  • Python: add ClickHouseMaterialized dataclass; generator applies Annotated[..., ClickHouseMaterialized("...")] and validates against default.
• E2E/Tests:
  • Expand schema definitions with MaterializedTest; add validation in e2e utils for column materialized.
  • Add extensive unit tests across Rust/TS/Python for materialized handling, SQL generation, diffing, and exclusivity rules.
• Docs:
  • New guides for Materialized Columns in TS/Python and Moose docs; navigation updated.
