Generates a static api_manifest.json from the library's descripex annotations.
The manifest is a JSON-serializable representation of every public function in the library — params, return types, errors, specs, and descriptions. Suitable for downstream codegen (generated contract bindings), agent discovery, validators, and contract-stability diffs across onchain version bumps.
mix onchain.manifest
mix onchain.manifest path/to/output.json
mix onchain.manifest --check
mix onchain.manifest --check path/to/output.json--check regenerates the manifest in memory and compares it against the
committed file, ignoring only generated_at. Exits non-zero with a
readable diff when they differ. Wired into mix ci so a descripex
upgrade or an api() edit cannot silently drift the artifact.
Uses Onchain.ABI.__descripex_modules__/0 as the single source of truth for which
modules to include. Output defaults to api_manifest.json in the project root.
