fix(architect): add pod_name to agent requests, rewrite foundary cookbook

The architect service was missing pod_name/namespace in AgentRequest
metadata, causing Claude Code adapter to reject all requests. Added
ArchitectServiceConfig with pod resolution (project PodName → default
claudebox-0). Removed silent JSON fallback in extractSpecFromMessages
that masked errors.

Rewrote foundary cookbook from 90-step SDLC flow to focused 25-step
cookbook using natural language build prompts instead of /slash-commands
that claudebox cannot execute. Added "no fallbacks" rule to CLAUDE.md.

 - **Migrations:** NEVER modify committed migrations. Create NEW ones.
 - **500-line limit:** Files exceeding 500 lines must be split
 - **Tests:** All handlers and services require tests
+- **No fallbacks:** NEVER design "try X, fall back to Y" flows — fix X. Fallbacks hide errors and deliver inferior experiences.
 - **Multi-step ops:** NEVER log-and-continue after partial failure. Rollback or document partial state.
 - **Logging:** Use `logging.FromContext(ctx)` or injected `*slog.Logger`. NEVER `fmt.Println`, `log.Fatal`, `log.Printf`, or bare `slog.Info()`. Error key is ALWAYS `"error"` (not `"err"`). Use field constants from `internal/logging/fields.go` (e.g., `logging.FieldProjectID`, `logging.FieldError`). Log once at boundary (handlers/workers log, services return errors). Sensitive data (passwords, tokens, keys) is auto-redacted.
 - **HTTP clients:** NEVER create `&http.Client{}` without a `Timeout` field. All HTTP clients must have explicit timeouts (30s standard, 5s for health checks). A bare client can hang indefinitely.
