Add tools/openapigen — a single-binary Go program that walks the
exported structs in database/model, web/entity, and xray via go/parser
and emits two committed artifacts under frontend/src/generated:
- zod.ts shared Zod schemas keyed off `validate:` tags (ports get
.min(1).max(65535), Inbound.protocol becomes a z.enum,
Node.scheme too, etc.)
- types.ts plain TS interfaces inferred from the same walk, so
consumers can import Inbound without dragging Zod along
The walker flattens embedded structs (AllSettingView.AllSetting),
honors json:"-" and omitempty, and accepts per-struct overrides so
the JSON-string-inside-JSON columns (Inbound.Settings/StreamSettings/
Sniffing, ClientRecord.Reverse, InboundClientIps.Ips) render as
z.unknown() instead of leaking the DB-storage type into the API
contract. Type aliases like model.Protocol are emitted as TS aliases
and Zod schemas in their own right.
Wires `npm run gen:zod` in frontend/package.json so the generator can
be re-run without leaving the frontend tree. The existing openapi.json
build (gen:api) is left alone for now; migrating the OpenAPI surface
to this generator is a follow-up.
PR2 of the planned Zod end-to-end rollout.
