  -----------
  fix(cache): synchronize cache and routing state

CAT requests, backend state changes, and poll publication accessed
shared cache and VFO routing fields without common synchronization.

Make the rig cache opaque and publish current, RX, TX, and split state
under one mutex. Use synchronized accessors and coherent snapshots
throughout compiled frontends and backends, separate assumed routing
from observed VFO freshness, and invalidate ambiguous operation results.

Keep publication cadence independent from cache freshness while
preserving the historical 1000 ms cache default. Add focused concurrency
regressions and an architectural guard against direct cache or routing
state access.

  docs(cache): document coherent snapshot semantics

Describe the consistency and freshness boundaries of full cache snapshots and distinguish the routing-only snapshot from the complete cached state.

  fix(guohetec): read cache before rig open

Add a synchronized internal cache getter that does not require an open
communication state. Use it for Guohetec fallback and paired-VFO reads
while preserving validation on the public cache API.
