Add RPC infrastructure and updated database

- RPC Phase 1: Protocol, server, client implementation
- Updated renumber.go with proper text reference updates (3-phase approach)
- Clean database exported: 344 issues (bd-1 to bd-344)
- Added DAEMON_DESIGN.md documentation
- Updated go.mod/go.sum for RPC dependencies
