The spec is now built from the same calls that register the routes, so it
can't drift from the router like the swag comments did (all /api/v1
routes were missing).
- /api/v1 endpoints are typed Huma operations; the spec is OpenAPI 3.1 at
/openapi.json (3.0 at /openapi-3.0.json, YAML too), docs at /docs.
/openapi and /swagger/* redirect there
- Bearer token security is declared per operation; token creation and
the new GET /api/v1/health are public
- Legacy routes use the same handlers, are hidden from the spec and keep
the Deprecation header
- /sync/reset is hidden (debug only); the /sync/new, /sync/quick and
/sync/new/full aliases are removed (use /sync and /sync/full)
- Invalid parameters return 422 (validation); every error is
{"error": "..."}; empty lists are [] instead of null
- /sync/progress is documented as progress or result (oneOf)
- Tests validate the spec and check real responses of every documented
operation against it (kin-openapi)
- Removed swag annotations, cmd/docs, echo-swagger and the swag tool
