Add TimeoutAgentExecution (22m) to handlers for synchronous SDLC
execution, and TimeoutAgent{Default,Medium,Heavy} (12/22/47m) to
workers for tiered agent task execution. Aligns with SDLC action
complexity tiers and prevents inline duration literals.

- Add WorkErrorCode type with RATE_LIMITED, AUTH_FAILED, TIMEOUT, STALE_WORKER, AGENT_ERROR, INVALID_SPEC
- Add ClassifyAgentError function to detect error patterns from stderr
- Add error_code column to work_queue table (migration 016)
- Add FailWithCode method to WorkQueue interface and implementations
- Update RequeueStaleWithIDs to mark permanently failed tasks with STALE_WORKER
- Add ErrorCode to BuildResult for API responses
- Update work executor to classify errors before failing tasks
This enables users to see actual failure reasons (e.g., "RATE_LIMITED") instead of
builds stuck in "running" state forever when Claude hits rate limits.

Adds the composable monorepo template system that generates project skeletons
with pluggable components (service, worker, app-react, app-astro, cli).
Key changes:
- Monorepo skeleton templates with shared pkg/, scripts/, and git hooks
- Component templates (service, worker, app-react, app-astro, cli) with
Dockerfiles, CI steps, and component.yaml manifests
- Component domain model with validation and dependency resolution
- Component handler endpoints for CRUD and composition
- Template provider extended with BuildComposableProject and component assembly
- Deployer extended with composable project deployment support
- Handler timeout constants (TimeoutFastLookup through TimeoutLongRunning)
- envutil package for centralized env var reads with defaults
- api.DecodeJSON helper for standardized request body decoding
- Standardized response helpers (WriteBadRequest, WriteNotFound, etc.)
- Replaced fullstack-app cookbook with composable-app cookbook
- Hardened handler timeouts, logging, and error responses across all handlers
