Add defensive null checks before dereferencing DeviceAPI::getBuddySharedPtr()
in the PlutoSDR input and output plugins.
DeviceAPI initializes the buddy shared pointer to nullptr, so a buddy may
exist before its shared state has been attached. This could result in null
pointer dereferences during device initialization, buddy thread
suspend/resume, or settings application.
Changes include:
- Validate buddy shared pointer in openDevice() and fail gracefully if absent.
- Guard suspendBuddies() and resumeBuddies() against null shared pointers.
- Skip buddies without shared state during applySettings() while logging a
warning.
- Prevent dereferencing null buddy shared pointers when restarting buddy
threads.
These changes improve robustness during PlutoSDR buddy initialization and
avoid crashes caused by partially initialized buddy relationships.

Fix multiple issues preventing SoapySDR output from producing RF:
- handleInputMessages() never called in DSP engine thread (Qt signal
lost without event loop) - scheduled properly
- setGain() moved to start() post-activation (pre-activation gain
silently fails on SoapyUHD)
- fullScale threshold corrected for CS16 format detection
- Timed first write pattern matching gr4-lora SoapySink
MCR pinning for SoapyUHD: inject auto_tick_rate=0 in
DeviceSoapySDR device-open path to prevent UHD from re-deriving the
master clock rate on set_tx_rate(), which breaks the decimator chain
and produces no RF. Also reads SDRANGEL_USRP_MASTER_CLOCK_RATE_HZ env
var for optional MCR override.
TX diagnostic counters: SoapySDROutputThread tracks packets,
underflows, errors. Exposed via REST as streamSettingsArgs
key-value pairs.
Add memory buffer to Logger, so last 500 log messages can be included in crash report.
Generate and include stripped pdb files so stack trace can include function names.
