Johnathan Corgan ce6dba9225 Add privacy considerations section to routing document
Documents the tradeoff between metadata privacy and route error feedback:
- Intermediate routers see src_addr/dest_addr (traffic analysis possible)
- Source address needed for CoordsRequired/PathBroken error messages
- Deliberate choice: explicit feedback over silent drops + app timeouts
- Partial mitigation: addresses are SHA-256(npub), not npubs themselves
- Notes onion routing as alternative with different tradeoffs
