* Implementation of Status Message
* Change drawNodeInfo to drawFavoriteNode
* Truncate overflow on Favorite frame
* Set MAX_RECENT_STATUSMESSAGES to 5 to meet memory usage targets
Add a meshtasticd config for the Luckfox Pico Max with the Waveshare Pico LoRa SX1262 TCXO HAT.
Tested on hardware with successful SX1262 init, broadcast, and direct messaging.
* fix(stm32/russell): define ENABLE_HWSERIAL2 and Serial2 pins
The Russell board variant was missed during Initial serialModule cleanup
(PR #9465), which began requiring Serial2 to be explicitly defined via
ENABLE_HWSERIAL2 and PIN_SERIAL2_TX/RX rather than relying on implicit
defaults, causing a build error.

* feat(stm32/russell): add BME680 support, exclude modules to fit flash
The BME680 is hardware footprint compatible with the BME280 already
present on the Russell board, so add it as an additional lib dep to
enable environment sensing (temperature, humidity, pressure,
gas resistance).
The STM32 target has very limited flash. Even traceroute alone causes
overflow, so the following modules are excluded to stay within budget:
- RANGETEST
- DETECTIONSENSOR
- EXTERNALNOTIFICATION
- POWERSTRESS
- NEIGHBORINFO
- TRACEROUTE
- WAYPOINT
AIR_QUALITY_SENSOR is also excluded as it requires the BSEC2 library
for real IAQ output, which alone overflows flash by ~44KB on this
target. The Adafruit BME680 library is used instead for raw sensor
readings.

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.

To save resources, some devices where LR11x0 was never an option
excluded it from compilation, using RADIOLIB_EXCLUDE_LR11X0 .
As we will soon have LR2021 support, apply the same treatment
to that chip to these devices, by adding RADIOLIB_EXCLUDE_LR2021

* 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.

This reverts commit 391928ed08.
Since esp32_https_server commit e2c9f98, this is no longer necessary.
Also, the esp32-common.ini '-include mbedtls/error.h' causes a build error
under IDF v5 (https://github.com/meshtastic/firmware/pull/9122#issuecomment-4185767085):
<command-line>: fatal error: mbedtls/error.h: No such file or directory
so this change fixes that error.
