refactor: spec-generator outputs from monolithic files to directory structure

Requirements, architecture, and epics now output as directories with
individual files per design point (_index.md + REQ-*.md/ADR-*.md/EPIC-*.md),
linked via relative paths for better referencing and downstream consumption.
Phase 6 handoff bridge simplified to read directly from individual EPIC files.

# Architecture Document Template (Directory Structure)
Template for generating architecture decision documents as a directory of individual ADR files in Phase 4.
## Usage Context
| Phase | Usage |
|-------|-------|
| Phase 4 (Architecture) | Generate `architecture/` directory from requirements analysis |
| Output Location | `{workDir}/architecture/` |
## Output Structure
```
{workDir}/architecture/
├── _index.md # Overview, components, tech stack, data model, security
├── ADR-001-{slug}.md # Individual Architecture Decision Record
├── ADR-002-{slug}.md
└── ...
