refactor: rename binary from quoteforge to qfs

- Rename cmd/server to cmd/qfs for shorter binary name
- Update all documentation references (README, CLAUDE.md, etc.)
- Update build commands to output bin/qfs
- Binary name now matches directory name

Usage:
  go run ./cmd/qfs              # Development
  go build -o bin/qfs ./cmd/qfs # Production
