1. /quit and /help commands restored:
- /quit: exits the interactive loop
- /help: shows formatted help box with available commands & tips
- Unknown commands get a friendly error pointing to /help
- Slash commands intercepted before LLM processing (no token waste)
2. Zero warnings across entire workspace (13 files fixed):
- Fixed ambiguous glob re-exports in gyandoot-core
- Added #[allow(dead_code)] on intentional dead fields
- Fixed unused imports, variables, and macros
- Fixed unused assignments in subagents
- cleaned up service.rs, profile, kanban warnings
install.sh now produces a completely clean build with zero warnings.
