Replace extract_schema with VIR schema path in bridge and tests Add schema_map module to baml_bridge_cffi that maps VIR schema to bex_program types, filtering @skip fields and propagating @alias, @description attributes. Replace extract_schema in initialize_engine with project_schema + schema_map. Update test infrastructure to use VIR schema. Delete extract_schema entirely.

Preserve field order when extracting from Pydantic models (#3067) ## Summary Fixes #3066 - Class fields were being rendered in alphabetical order instead of declaration order in Python. This is a follow-up to #1931 which was an incomplete fix. While that PR correctly changed the `fields` variable to use `IndexMap`, the extraction from Python still used `BTreeMap<String, PyObject>`, which sorts keys alphabetically and destroys the original field order before it reaches the `IndexMap`. ## Changes - Add `indexmap` feature to pyo3 in `engine/language_client_python/Cargo.toml` - Change `BTreeMap` to `IndexMap` when extracting `model_fields` from Python in `parse_py_type.rs` - Improved the existing test by using field names (`c`, `b`, `a`) that would be reordered by alphabetical sorting, making the test actually catch this class of bugs ## Test plan - [x] Verified test fails with `BTreeMap` (fields rendered as `a, b, c`) - [x] Verified test passes with `IndexMap` (fields rendered as `c, b, a`)  --- > [!NOTE] > Fixes field ordering bug in Pydantic model extraction by replacing BTreeMap with IndexMap, ensuring fields maintain their declaration order instead of being alphabetically sorted. > > <sup>Written by [Mendral](https://mendral.com) for commit c25d2ebda497f3536dcd7a005b9dc31b79c7b492.</sup>

Improve test block validation (#3065) - Test block errors become warnings (to not block generation) - Test args must only have fields that match the params of the function under test - Test args must have fields for every non-empty param of the function under test - Test args must be parseable into the required types - Warnings in `baml-cli check` will return with non-0 exitcode  --- > [!NOTE] > Improves test block validation by adding checks for missing/unknown arguments and type validation, converting test errors to warnings to avoid blocking code generation > > <sup>Written by [Mendral](https://mendral.com) for commit 4eb8fab447fd3c91f6a49b7543fcb7315d70e434.</sup>

higher order functions (#3062) Add higher-order functions to the syntax of type signatures. They are already handled correctly in the typechecker, though likely not supported in bex yet.  --- > [!NOTE] > Add higher-order function types to BAML's type system, including parser support for `(x: int, y: int) -> bool` syntax, HIR/TIR representation, proper subtyping with variance rules, and pretty-printing. This update also adds support for parenthesized unions like `(A | B)` to work correctly with the new parser structure. > > <sup>Written by [Mendral](https://mendral.com) for commit 2f544367ceb3b08889053ff3dad10efac130da88.</sup>
