oxide-gen — Spec-to-Crate Generator

oxide-gen ingests an API specification (OpenAPI 3.x, GraphQL SDL, or a .proto file) and produces a self-contained Rust crate consisting of:

• Type-safe Rust structs / enums for the spec's data models.
• A reqwest-based asynchronous client (for OpenAPI and GraphQL) or a tonic-shaped scaffold (for gRPC) with one method per operation.
• A clap CLI that exposes every operation as a subcommand.
• A SKILL.md file with YAML frontmatter for Claude Code.
• An mcp.json file describing the CLI as MCP-callable tools.
• A module.json manifest that the [oxide_k] kernel can discover and register as a module.

The crate exposes three layers:

• [parsers] — spec format ↔ [ir::ApiSpec].
• [emit] — [ir::ApiSpec] → on-disk artifacts.
• [generate_from_path] — convenience entry point that auto-detects the spec format from the file extension and runs the full pipeline.
