feat(ADR-262 P1): wifi-densepose-rufield bridge — RuView sensing → signed RuField FieldEvents (fail-closed privacy map) (#1070)

* feat(rufield): ADR-262 P1 — wifi-densepose-rufield anti-corruption bridge

New v2 workspace member that converts RuView WiFi-CSI sensing output into
signed RuField FieldEvents. Path-deps the vendor/rufield submodule crates
(rufield-core/-provenance/-privacy/-fusion); single coupling point between
RuView and the standalone RuField MFS spec (ADR-262 §5.4).

- SensingSnapshot: owned primitives mirroring SensingUpdate + TrustedOutput
  (no dependency on wifi-densepose-sensing-server).
- snapshot_to_field_event(): builds a WifiCsi FieldTensor + Observation,
  derives a real position from the signal-field peak (never fabricated),
  real sha256 provenance + ed25519 signature (synthetic=false).
- map_privacy() (§3.3 crux): maps by information content, NEVER byte value —
  Derived (byte 1) → P4/P5, never P1; fail-closed demotion floor to P2.

P1 gates (tests/p1_gates.rs): round-trip serde, is_fusable verified receipt,
RuFieldFusion::ingest accept + infer runs, privacy-safety (Derived never P1),
full §3.3 table, fail-closed demotion, determinism, no-fabricated-position.
15 tests pass (5 unit + 9 integration + 1 doc), 0 failed.

Honesty: P1 plumbing (tested conversion + safe privacy mapping), NOT wired
into the live server (P3) and NOT an accuracy claim.

* docs(adr-262): mark P1 implemented + CI submodules:recursive + CHANGELOG/CLAUDE

- ADR-262 Status → "Proposed — P1 implemented"; add §0.1 Implementation
  status (the bridge crate + the five P1 gates that pass; defers the
  provenance-carrier reuse, P3 live wiring, and P4 multi-modality).
- ci.yml: add `submodules: recursive` to the rust-tests checkout so the new
  crate's `vendor/rufield` path-deps resolve in CI (they fail otherwise even
  though the workspace build passes locally with the submodule present).
- CHANGELOG [Unreleased]: P1 bridge entry (kept alongside the upstream
  ADR-262 research entry).
- CLAUDE.md: crate table row for `wifi-densepose-rufield`.
