The CALIBRATE_ALL (0x7F) command inside resetAGC() clears bit 0 of the
undocumented 0x8B5 register. That bit is set once in init() by #9571 and
#9777 to improve SX1262 RX sensitivity, and the AGC-reset path was not
re-applying it. Result: every SX1262 node silently loses the RX
sensitivity patch ~60s after boot and never recovers until reboot.
Empirically confirmed on Heltec Mesh Node T114 (nRF52840 + SX1262):
- Post-calibration read of 0x8B5 = 0x04 (bit 0 cleared)
- After re-apply: 0x05 (bit 0 set)
Reproducible every AGC_RESET_INTERVAL_MS tick.
Fix re-applies the register bit alongside the existing post-calibration
re-applies (setDio2AsRfSwitch, setRxBoostedGainMode).

The linker script was created by merging variants/STM32WLxx/WL54JCI_WL55JCI_WLE4J(8-B-C)I_WLE5J(8-B-C)I/ldscript.ld and system/ldscript.ld from stm32duino/Arduino_Core_STM32.
mallinfo().fordblks counts only free bytes within the committed arena.
On STM32WL (newlib sbrk heap) the arena grows lazily from _end toward SP,
so fordblks reads near-zero at early boot even when ~48 KB of addressable
space remains. This caused NodeDB::isFull() to fire prematurely and evict
nodes on a freshly booted device.
Fix getFreeHeap() to include uncommitted sbrk headroom (SP - sbrk(0)) so
the returned value reflects true available memory throughout the boot
lifecycle.
Introduce MESHTASTIC_DYNAMIC_SBRK_HEAP as an opt-in build flag (set in
stm32.ini) so the fix is gated to platforms with a dynamic sbrk heap
rather than a static heap. Future platforms with the same heap model can
opt in by adding this flag.

Integrate STM32 battery monitoring into AnalogBatteryLevel, supporting
external GPIO ADC pins as well as internal VBAT channel.
Features:
- ADC reading using STM32 LL (Lower Layer) macros supporting external
ADC channels and internal VBAT channel (AVBAT)
- ADC compensation using STM32 LL macros with factory-calibrated VREFINT
(AVREF) for accurate voltage measurement
- LFP battery OCV curve for STM32WL using AVBAT (STM32 VDD absolute
maximum supply voltage 3.9V, direct connection of Li-Po batteries is
not supported)
Internal VBAT channel implemented in:
- Russell
- RAK3172
In these variants, ADC_MULTIPLIER = (1.01f * 3) = 3.30 as there is a
3:1 internal divider (DS13105 Rev 12 §5.3.21), and a bit of tolerance
as the actual 10% spec leads to readings much too high.

* fix(native): implement BinarySemaphorePosix with proper pthread synchronization
The BinarySemaphorePosix class (used on all Linux/portduino/native builds)
had stub implementations: give() was a no-op and take() just called
delay(msec) and returned false. This broke the cooperative thread scheduler
on native platforms — threads could not wake the main loop, radio RX
interrupts were missed, and telemetry never transmitted over the mesh.
Replace the stubs with a proper binary semaphore using pthread_mutex_t +
pthread_cond_t + bool signaled:
- take(msec): pthread_cond_timedwait with CLOCK_REALTIME timeout, consumes
signal atomically (binary semaphore semantics)
- give(): sets signaled=true, signals condition variable
- giveFromISR(): delegates to give(), sets pxHigherPriorityTaskWoken
Tested on Raspberry Pi 3 Model B (ARM64, Debian Bookworm) with Adafruit
LoRa Radio Bonnet (SX1276). Before fix: no radio TX/RX, no telemetry on
mesh. After fix: bidirectional LoRa, MQTT gateway, telemetry all working.
