fix: include schemas in crates.io package via build.rs

Schemas from the acp-spec submodule are now copied to schemas/v1/
at build time, ensuring they're included in the crates.io package.

- Add build.rs to copy schema files from submodule
- Update include_str! paths to use vendored location
- Add schemas/ to .gitignore (generated at build time)
- Add include list to Cargo.toml for packaging
