- Change > to >= so stored value 1 means direct/0-hop only (liamcottle)
- Clamp max_hops to 63 on write since getPathHashCount() caps at 63 (robekl)
- Update comments to reflect encoding: 0=no limit, 1=direct only, N=up to N-1 hops

Filter auto-add of new contacts by hop count (issues #1533, #1546).
Setting is configurable from the companion app via extended
CMD_SET/GET_AUTOADD_CONFIG protocol (0 = no limit, 1-63 = max hops).

Pin mapping verified against HTIT-Tracker V0.5 schematic:
- GPIO35 (GPS_EN): N-ch MOSFET drives P-ch high-side switch, active HIGH
- GPIO36 (GPS_RST): hardware reset, active LOW
- GPIO33/34: UART TX/RX
Delegates power management to MicroNMEALocationProvider begin()/stop()
which independently controls GPS power via GPS_EN and shares VEXT with
the display through RefCountedDigitalPin.
The GC1109 FEM needs its VFEM_Ctrl pin held HIGH during deep sleep
to keep the LNA active, enabling proper RX sensitivity for
wake-on-packet. Without this, the LNA is unpowered during sleep
and RX wake sensitivity is degraded by ~17dB.
Release RTC holds in begin() after configuring GPIO registers
(not before) to ensure glitch-free pin transitions on wake.
Trade-off: ~6.5mA additional sleep current for significantly
improved wake-on-packet range.
* companion: new field in CMD_SET_OTHER_PARAMS, path_hash_mode
* companion: CMD_SEND_SELF_ADVERT, cmd_frame[1] now holds the path hash size (0 = zero hop, 1..3 = flood path hash size)
PacketQueue::countBefore() and PacketQueue::get() use unsigned
comparison (_schedule_table[j] > now) to check if a packet is
scheduled for the future. This breaks when millis() wraps around
after ~49.7 days: packets scheduled just before the wrap appear
to be in the far future and get stuck in the queue.
Use signed subtraction instead, matching the approach already used
by Dispatcher::millisHasNowPassed(). This correctly handles the
wraparound for time differences up to ~24.8 days in either
direction, well beyond the maximum queue delay of 32 seconds.
PacketQueue::add() silently dropped packets when the queue was at
capacity. The packet pointer was lost — never enqueued, never returned
to the unused pool. Each occurrence permanently shrank the 32-packet
pool until allocNew() returned NULL and the node went deaf. Return bool
from add() and free the packet back to the pool on failure.
