docs/hardware.md is the single place a reader goes to put MeshTerm on a
PicoCalc or a uConsole, written in the shape of the command-line manual: what
the three targets are and which exclude each other, why the console font is
built on the device, every phase of the Calculinux bring-up and its knobs, the
XIAO UART radio from parts to a verified link, the SPI bridge with an honest
note that it was written against pymc_core 1.0.x while today's uConsole stack
depends on the renamed openhop-core, and a closing list of what has only ever
been proven on one bench. scripts/README.md and xiao-radio/README.md become
short indexes pointing at it; the old ones were stale in four places (trace
through the bridge works, the firmware env is _serial, two scripts were
unlisted). README links the manual, gains the two dependency rows it lacked
(markdown-it-py, PyYAML) and a fixed fonts anchor.
