Adds the Traffic Management module (TMM) plus the NodeDB/warm-store and
next-hop foundations it builds on:
- Unified per-node cache (flat array, 8-bit relative ticks) shared by all
features; role-aware throttles for tracker / lost-and-found.
- Position deduplication: drop unchanged position rebroadcasts within a
configurable interval; precision driven off the channel ceiling (clamped to
the public-key max on well-known channels). Enabled by default at 11h.
- Per-node rate limiting and unknown-packet filtering (config-driven; a
non-zero companion field enables each feature -- no bool toggles).
- NodeInfo direct response from cache with role-based hop clamps.
- Persistent next-hop overflow store: confirmed hops have no TTL, are seeded
from NodeInfoLite at boot, and survive hot-store eviction.
- Three-tier sender-role resolution (hot NodeInfoLite -> warm store -> TMM
cache). Role is cached write-time (seeded on first track, refreshed from
NodeInfo), pins its cache entry like a next-hop hint, and is evicted last.
- Warm store caches device role + protected category across reboot/eviction.
- PositionModule stationary floor for tracker / lost-and-found.
- PSRAM gating for warm/satellite/TMM cache sizes; STM32WL excluded.
Protobufs: TrafficManagementConfig trimmed to the five uint32 fields actually
used; submodule repointed to protobufs develop.
