[AZ-428] [AZ-429] [AZ-430] [AZ-431] Add NFT-PERF-01..04 perf scenarios

Batch 85 — 4 Performance NFT scenarios + pure-logic evaluators.

- NFT-PERF-01 (AZ-428, Tier-2): two-config e2e latency p95 ≤ 400 ms
  (K=3@25°C, K=2 hybrid@50°C) + frame-drop ≤10% + informational per-stage
  partition recording (D-CROSS-LATENCY-1).
- NFT-PERF-02 (AZ-429): inter-emit p95 ≤ 350 ms + no ≥3 missed-emit
  windows. fc-adapter-aware SITL timestamp extraction (tlog vs MSP).
- NFT-PERF-03 (AZ-430, Tier-2): cold-start TTFF p95 ≤ 30 s AND max ≤ 45 s
  over N≥10 iterations.
- NFT-PERF-04 (AZ-431): spoof-promotion latency p95 ≤ 600 ms over N≥20
  randomized-start blackout+spoof events.

All scenarios consume external fixtures (AZ-595 dependency surfaced) and
fail loudly when fixtures are missing or empty. Public-boundary
discipline preserved — evaluators do NOT import src/gps_denied_onboard.

Tests: 60 new unit tests pass; 24 scenarios collect (4 tests × 2 fc × 3
vio). Code review: PASS_WITH_WARNINGS — 1 Medium (fixed in batch),
3 Low (production-dependency surfacings + future hygiene).
