v1.4.0 — Document Archiving System

Document Archiving System

Add a document archiving layer to the project memory stack.

New files:

• docs/ directory — organized document storage with 6 preset type subdirectories
• DOCS.md — document index with metadata (title, status, last updated, sub-doc hierarchy)
• references/document-archiving.md — archiving protocol with auto-classification rules

6 preset document types (selected during init, extensible):

• PRD, Tech Design, Design Docs, Research, Meeting Notes, Experiments

End session integration:

• New step 7.5: auto-detects document output, classifies by type, archives to docs/, updates DOCS.md index
• Documents support main + sub hierarchy (e.g., docs/prd/main.md + docs/prd/auth-module.md)

Safety:

• docs/ excluded from file reorganization — managed independently by DOCS.md
• Upgrade mode: creates DOCS.md with defaults (PRD, Tech Design, Research)
