jackandClaude Fable 5 e0e90af9fd Integration test fixes: reconcile SyncTypeFlags phantom-bit assertions and sync-round counts
- SyncTypeFlags phantom-bit tests used bits 8/9/10 as unmapped examples;
  board/prekey/group now map those, so use bits 11+ (still unmapped).
- rawValueInitNormalizesPhantomBits: highest known bit is now 10, so the
  flags serialize to 2 bytes, not 1.
- Board/fragment/announce sync tests silence the prekey round (added by the
  prekeys feature; default 60s schedule fires at the maintenance barrier).
- DiagnosticsMockContext: conform to the CommandContextProvider members added
  by private-groups (group*) and cashu-chips (sendPublicMessage).
