chore: release v0.20.11

Confirmed from an FT-891 CAT log: OpsLog tuned via OmniRig's SetSimplexMode,
which returned OK on every spot click but never moved the VFO (readback stayed
put), while SetMode on the same .ini worked — so the CAT link was healthy and
only the frequency write was a no-op. SetSimplexMode was chosen because Icoms
accept direct FreqA writes but don't move; Yaesu/Kenwood are the opposite.

Now, for non-Icom rigs (or if SetSimplexMode errors), also write the VFO
frequency property (FreqA/Freq) directly, which does move them. Icom keeps the
SetSimplexMode-only path so the Main/Sub VFO isn't nudged by a direct write.
