EnvironmentLoader.Load() previously returned (empty Catalog, nil) on all
failure paths, making it impossible for callers to distinguish "no services
available" from "discovery failed due to auth/network issues".
Changes:
- Add CatalogDegraded error type with three reasons: unauthenticated,
market_unreachable, runtime_all_failed
- Add auth pre-check: return DegradedUnauthenticated immediately when no
token is available, avoiding doomed MCP connections
- Schema command now handles CatalogDegraded gracefully: outputs hint to
stderr and includes degraded/reason/hint fields in JSON output
- Runner preserves graceful degradation by ignoring CatalogDegraded errors
- Skip empty-products cache to prevent stale cache from masking auth errors
- Edition-aware hint text (open-source vs embedded/wukong)
Made-with: Cursor
- Support schema output in table format for human-readable display
- Add product-level endpoint loading in CLI loader
- Wire schema-text rendering into runner output pipeline
- Add priority field support for todo task helper
- Build tool → endpoint mapping from CLI tools and overrides
- directRuntimeEndpoint resolves by tool name before product fallback
- Support dynamic command routing with compat layer updates
- Add StdinGuard for safe single-read stdin across multiple flags
- Add ResolveInputSource unified resolver for @file, @-, and pipe
- Support @file / @- syntax for all string-typed override flags
- Remove unused writeSchemaText function
- Add stdin.go with ReadStdinIfPiped and ReadFileArg helpers
- Support @file syntax for --json flag to read payload from file
- Fall back to stdin pipe when no --json argument is provided
