ruv e764504dc5 test(adr-110): lock NodeSyncSnapshot JSON wire contract (iter 24)
Iter 24 — ultra-opt for public-API stability. Iter 23 added a new JSON
field that UI clients (viz.html, future Tauri desktop, automation) now
depend on; this iter locks its exact shape so any future rename /
removal fails a named test instead of silently breaking consumers.

New module `node_sync_snapshot_serialization_tests` (3 tests, all green):

  * sync_present_serializes_all_seven_fields
      Builds NodeInfo with Some(sample_sync), serializes to serde_json::Value,
      asserts all 7 documented field names exist (offset_us, is_leader,
      is_valid, smoothed, sequence, csi_fps_ema, csi_fps_samples) and
      spot-checks numeric values.

  * sync_absent_omits_the_key_entirely
      Builds NodeInfo with sync = None, asserts the `sync` JSON key is
      DROPPED entirely (not emitted as `"sync": null`). This is the
      backwards-compat contract that lets pre-iter-23 UI clients ignore
      mesh-aware nodes silently.

  * sync_round_trips_through_serde
      to_string / from_str round-trip on a populated NodeInfo recovers
      every field of the sync sub-object byte-for-byte (modulo float tol).

Test infrastructure: pure pure serde_json — no network, no fixtures,
no I/O. Adds 92 lines, 0 runtime allocs in the steady path.

Branch-coord clean (no Cargo.toml or cli.rs touched).
