Adds a user-configurable toggle for how each peer-to-peer service
reaches federated peers. Three options per service:
- Auto (default) — FIPS preferred, Tor fallback (current behavior).
- FIPS only — fail rather than fall through to Tor.
- Tor only — explicit opt-in to onion anonymity for that service.
Services covered (matching the UI rows):
- Federation — state sync, invites, peer notifications
- Peers — address/DID rotation broadcasts
- Peer Files — content catalog download/browse/preview
- Messaging — archipelago channel + mesh bridge
- Mesh File Sharing — content_ref blob fetches
Implementation:
- settings::transport — persisted struct + process-wide OnceLock handle
(so deep call sites don't need data_dir threaded through signatures).
On-disk file: <data_dir>/settings/transport_preferences.json; missing
or corrupt → defaults (Auto everywhere).
- settings::transport::init() called from main.rs after config load.
- fips::dial::PeerRequest gains a .service(kind) builder; send_* checks
the preference before choosing a transport. FIPS-only fails loudly
when FIPS is unavailable (so users who pick it know when something
falls back).
- Every FIPS-first migration site tags its PeerRequest with the
matching PeerService so the toggle actually applies.
- transport.preferences + transport.set-preference RPCs added; wired
into the dispatcher.
- neode-ui/src/views/settings/TransportPrefsCard.vue — standalone card
with a 5-row Auto/FIPS/Tor tri-state. Not wired into Settings.vue —
the user places components themselves (see feedback_ui_entry_points).
