* Right-size nRF52 heap tiers after 2.8.0 heap-exhaustion field reports
Field reports on 2.8.0 show nRF52840 devices at 99% heap (114/115 KB)
within minutes of boot; operator new asserts on OOM, so these devices
are one allocation from a reboot. The 2.8.0 cache sizing ladders gave
nRF52 the largest non-PSRAM tiers on the assumption that a BLE-only
part has a roomy heap - the arena is actually ~125 KB shared with the
FreeRTOS task stacks.
Per-target retiers (nRF52840 unless noted):
- Traffic Management cache 1000 -> 250 entries (10 KB -> 2.5 KB); the
unclassified fallthrough drops 1000 -> 400 to match the classic-ESP32
tier (also affects RP2040/RP2350)
- Warm node store 200 -> 100 entries (8 KB -> 4 KB); the non-XXAA
fallthrough drops 320 -> 100 so an unclassified RAM-constrained part
can't boot-allocate 12.8 KB
- MESSAGE_HISTORY_LIMIT 20 -> 10 (text pool 4.4 KB -> 2.2 KB), the tier
classic ESP32 already ships
- MAX_RX_TOPHONE 32 -> 16, shrinking the static packet pool 70 -> 54
slots (~6.6 KB of .bss returned to the heap arena)
- PacketHistory hash index off arch-wide (1 KB); O(n) over 240 records
is negligible at LoRa packet rates
- OLEDDISPLAY_REDUCE_MEMORY arch-wide (~1 KB OLED back buffer); the five
TFT variants -U it because TFTDisplay.cpp needs buffer_back for
dirty-window diffing
- Drop the stale "for testing" 1024-entry TMM override on T1000-E
Measured on rak4631: heap arena grows 124,572 -> 131,180 B and boot
allocations drop ~15.7 KB, roughly +22 KB free heap on the field-report
device class.
Migration: the nRF52840 warm flash ring replays through place() (LRU),
so the newest 100 identities survive the shrink; the file backend
rejects oversized snapshots cleanly (new test covers this). Native
suites pass (536/536 Docker, 13/13 native-macos warm store); rak4631,
heltec-mesh-node-t114 (TFT) and tracker-t1000-e build green.
* Drop stale OLEDDISPLAY_REDUCE_MEMORY -U on t114 / mesh-solar-tft
Only USE_TFTDISPLAY variants (t1, t096, wismeshtap) compile
TFTDisplay.cpp and need the lib's buffer_back; t114 and mesh-solar-tft
render through the meshtastic-st7789 driver, which handles the
reduced-memory configuration fine - as #10894 (merged from develop)
already established by defining the flag there. Remove the -U guard and
the per-variant -D (redundant with the arch-wide define in nrf52_base
on this branch). Both variants verified building.
* True Colors on TFT (Heltec Mesh Node T114, Heltec Vision Master T190, CardPuter Adv, T-Deck, T-Lora Pager)
* Theme support - New and some Classic Themes!
* Colored Compass

I thought git would be smart enough to understand all the whitespace changes but even with all the flags I know to make it ignore theses it still blows up if there are identical changes on both sides.
I have a solution but it require creating a new commit at the merge base for each conflicting PR and merging it into develop.
I don't think blowing up all PRs is worth for now, maybe if we can coordinate this for V3 let's say.
This reverts commit 0d11331d18.

* Make RAK4631 nodes power back on deep sleep
The devices will hang if the VBAT goes under 1.7V (Brown-out reset) and
they will never come back unless power supply goes completely off.
This kills unattended nodes.
Using the SystemOff the LPCOMP we can get the nodes back again when
power comes back, even if VBAT goes under 1.7V, which moreover is more
unlikely because the device is off.
* Adding support for heltec t114
And moved particularities to variant.h
* Remove old cpp comment that belongs to variant.h
It was a leftover.
* Trunk fix
