Add generate_routes(template_style=...) and CLI --template-style. When on,
stubs use async def, a JSON body parameter named body (dict or Model), and
with --inject-request a service-lookup hint comment before NotImplementedError.
Default behaviour (def/payload) unchanged. +2 tests (32 passed), wiki + MCP
bundle regenerated.
codegen_routes.generate_routes now sanitizes resource identifiers (fetch-requests -> fetch_requests), optionally prepends 'request: Request' (inject_request) and emits <resource>/routes.py packages with __init__.py (package). multipart/form-data and x-www-form-urlencoded bodies expand to per-property UploadFile/File/Form params instead of an opaque dict; spec paths are normalized to forward slashes to avoid Windows escape issues. Adds CLI flags --inject-request/--package, 7 focused tests, and refreshes lib/wiki/MCP docs to the real CLI.
