v0.4.0

What's Changed

Added

• Knowledge cards fully wired into the incremental update flow: update maps changed files against the knowledge plan — cards whose source_files changed and modules whose scope was touched each get a refresh task (card updates carry an "Update Summary" section, enforced by check) (1031ce7)
• site renders knowledge module docs and cards under a dedicated "Knowledge Base" nav chapter — searchable, with source popups and mermaid; card front matter is stripped for display (1031ce7)
• update re-arms done update tasks across finalize epochs with freshly regenerated specs — previously the second update round silently did nothing (1031ce7)
• Knowledge YAML exports fill source_files in _index.yaml / _module.yaml (union of card source files under each module's scope) (1031ce7)

Fixed

• Removed unreachable dead code in knowledge.py (1031ce7)
