Crate kb 

Personal knowledge base — typed AST with org-mode as projection, SQLite-backed.

The crate provides:

• parser — org-mode text → AST
• generator — AST → org-mode text
• storage — SQLite persistence with FTS5 search
• api — HTTP handlers for kb-server
• mcp — Model Context Protocol server over stdio

The org-mode AST types are re-used from the companion tftio_org crate; the parser is kept in-crate (see the crate README for the rationale).
