The four capabilities that kept third-party apps a sketch of a built-in one:
* wada.map the firmware's own tiles, projection and cache inside an app
page, with its own capped pool so it never evicts the Map tab's
* wada.ui.list the missing "pick one of N" widget; rows are real buttons, so
keyboard and trackball nav walk them for free
* on_packet each frame delivered once instead of polling a 16-deep ring,
which sampled rather than observed
* wada.mesh.discover the active zero-hop probe, behind its own permission
because it spends every neighbour's airtime, not just ours
Plus the surface those need to be useful: packet identity reported only where
the frame actually carries it, exact micro-degree coordinates (Lua is built
LUA_32BITS, so its floats were quietly costing a metre), altitude and satellite
time, wada.geo, wada.ui.input, named and one-shot timers, http_post, windowed
fs.read, and wada.sys.env on a hardware gate rather than the memory one.
Fixes:
* Both ESP32-P4 targets could not link. g_wifi_last_disc_reason was defined in
src/main.cpp, which the IDF builds never compile, so all nine S3 envs stayed
green while Tanmatsu and T-Display P4 were dead.
* Map zoom level was invisible in +/- buttons mode; the readout was hidden with
the slider it was anchored to.
* Hungarian and Dutch held each other's "No SD card" translation.
