docs: ASCII typography and style normalization across all repo text

Browse Source 
Replace every em dash with real punctuation (rewrites, not hyphen swaps)
in docs, code comments, scripts, configs, and the port records; convert
en dashes, curly quotes, ellipsis glyphs, arrows, and section signs to
ASCII; drop machine-writing tell phrases from living docs. ADR titles
now use a colon. The M2 bring-up DTS model string carried an em dash
into the patch series and its record echoes; fixed at both, and the full
series re-verified to apply cleanly onto pristine 6.18.46. One comment
in freshness.h deliberately names the em dash glyph the UI renders as
the unknown mark; that is data, kept as prose naming it.

Verified: cargo tests (sim, config-lint, rs485-bridge), shellcheck,
both driver MC/DC harnesses, patches-apply.

## The honest ceiling (why "100% open NPU" stops at the driver)
The kernel driver only DMAs an opaque userspace-authored `regcmd` blob into the PC
registers and pulses go — it never inspects the compute stream. The compute-engine
registers and pulses go. It never inspects the compute stream. The compute-engine
register map (TRM Part 2) is not public for RV1106, there is **zero open RE prior
art** for this NPU generation, and only the closed RKNN-Toolkit2 compiler emits
valid regcmd. Mainline `accel/rocket` + Mesa Teflon are RK3588-only (64-bit). So an
