* Initial commit for a2ui_restaurant_finder and a generic a2UI extension.

* Update spec.md with catalog definition.

* Only have data fetch be a tool. Pass the UI requirements in the prompt.

…tity naming rules

Establish formal Unicode Standard Annex a2ui-project#31 (UAX a2ui-project#31) variable naming constraints across all A2UI v0.10 catalog entities, including component names, function names, and argument keys.

- Update `a2ui_protocol.md` and `basic_catalog_implementation_guide.md` with explicit Unicode character property rules (`XID_Start`, `XID_Continue`) and canonical URLs.
- Implement exhaustive deep schema property verification in `specification/v0_10/test/run_tests.py` using Python's native `isidentifier()` validation.

…2ui-project#31 validation

Address code review feedback on PR a2ui-project#1573:
- Update `specification/v0_10/docs/a2ui_protocol.md` to define `functions` as an object map instead of an array, ensuring full alignment with catalog JSON schemas, and clarify runtime execution boundary determination.
- Refactor `specification/v0_10/test/run_tests.py` to correctly iterate over `functions` as a dictionary map, ensuring exhaustive deep property traversal (`check_schema_properties`) across all function definitions.

* feat(specification): designate Unicode UAX #31 catalog entity naming rules

Establish formal Unicode Standard Annex #31 (UAX #31) variable naming constraints across all A2UI v0.10 catalog entities, including component names, function names, and argument keys.

- Update `a2ui_protocol.md` and `basic_catalog_implementation_guide.md` with explicit Unicode character property rules (`XID_Start`, `XID_Continue`) and canonical URLs.
- Implement exhaustive deep schema property verification in `specification/v0_10/test/run_tests.py` using Python's native `isidentifier()` validation.

* fix(specification): reconcile functions map structure and python UAX #31 validation

Address code review feedback on PR #1573:
- Update `specification/v0_10/docs/a2ui_protocol.md` to define `functions` as an object map instead of an array, ensuring full alignment with catalog JSON schemas, and clarify runtime execution boundary determination.
- Refactor `specification/v0_10/test/run_tests.py` to correctly iterate over `functions` as a dictionary map, ensuring exhaustive deep property traversal (`check_schema_properties`) across all function definitions.

- Update protocol version metadata to 1.0 and status to Candidate.
- Consolidate major changes overview into five high-level architectural pillars.
- Document the built-in @index iteration index function.
- Reconcile catalog entity naming rules with Unicode UAX a2ui-project#31 standard.
- Update basic catalog version identifier URI.

Variable identifiers now strictly conform to the Unicode Identifier standard (UAX a2ui-project#31), allowing Unicode letters, digits, and underscores, but forbidding dashes (-). This prevents naming ambiguity with future expression/subtraction syntax support.

- Update identifier regex pattern to `[^\W\d]\w*` in `compiler.py`.
- Document identifier rules in `a2ui_express.md` and `prompt_generator.py`.
- Convert all example `.a2ui` variables and `.json` component IDs to use underscores instead of dashes.
- Refactor python tests in `test_express.py`.

BREAKING-CHANGE: Separators like dashes (`-`) are no longer permitted in A2UI Express variable names. Existing DSL definitions containing dashes in variables will fail parsing.

…31 validation

- Add generic Catalog[TComponentApi, TFunctionApi] supporting dynamic composition and ID aliasing.
- Enforce UAX #31 identifier validation threshold for protocol versions >= 1.0.
- Add FunctionReturnType, InferA2uiReturnType, AllowedCallers, and bounded TReturn generic parameter to FunctionImplementation.
- Update Pydantic schema generator scripts for allowedCallers model validation on FunctionDefinition.
- Regenerate schema models for v0.8, v0.9, and v1.0.
