feat(hogql): add native compiler frontend

[bill-ph]

Description

Managed-warehouse clients can submit HogQL directly to Trino without Python-side SQL rendering.

• The statement protocol accepts typed, versioned HogQL requests and returns normal Trino query results or diagnostics.
• The native parser and compiler lower HogQL syntax, functions, properties, joins, modifiers, parameters, and semantic relations into stock Trino AST nodes.
• The coordinator consumes authenticated, pinned semantic catalogs from Duckgres and rejects stale or incompatible generations.
• Bounded caches, refreshes, queues, payloads, diagnostics, and metrics keep compilation isolated from normal SQL execution.
• DuckLake compatibility functions preserve supported ClickHouse semantics where stock Trino has no equivalent.
• Parser, compiler, planner, endpoint, benchmark, and exact-image tests cover the native request path.

Warning

Merge and deploy Duckgres #1134 before this branch. The native frontend depends on that endpoint.

Additional context and related issues

• The implementation keeps authorization and tenant guards in Duckgres and Trino rather than the language compiler.
• Full Maven reactor and exact-image compatibility validation ran locally.
• Codex implemented the change from an engineer-approved milestone plan.
• The writing-pr-descriptions skill shaped this description.
