# Regenerate the OpenAPI spec and all derived artefacts from the current server code.
#
# Run this after any change to fynd-rpc-types or fynd-rpc that affects the API
# surface (new fields, new endpoints, changed types):
#
#   ./scripts/update-openapi.sh
#
# What it does:
#   1. Builds the server binary and exports the OpenAPI spec to clients/openapi.json
#   2. Regenerates clients/typescript/autogen/src/schema.d.ts via openapi-typescript
#
# Requirements:
#   - Rust toolchain (cargo)
#   - openapi-typescript (npx will download it on first use)
