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.

# RV1106 hardware-capabilities audit — nothing left on the table
# RV1106 hardware-capabilities audit: nothing left on the table
Every block in the vendor SoC DT (`rv1106.dtsi`), classified. Goal: a 6.18 driver
for every capability the hardware actually has, open-source, verified. Camera/ISP
is the only whole class deliberately skipped — the 86-Panel has no camera.

## VOP display: VERIFIED this run (2026-08-25)
Full WardenOS Dashboard renders on the 86-Panel on 6.18 (`_b`), webcam-verified,
pixel-identical to stock `_a`. Two VOP driver bugs were the final black-screen
cause: `rgb_dclk_pol` hardcoded inverted (panel needs 0), and the wrong primary
scanout window (rv1106 uses **WIN1**, not rv1126's WIN2). Full chain + `_a`-vs-`_b`
register diff in `display/VERIFIED.md`.

## GT911 touch: VERIFIED this run (2026-08-25)
UI responds to taps/swipes on the panel (confirmed by hand at the panel); GT911 detected
(`ID 911, version 1060`), `/dev/input/event0` held by warden-ui. Fix:
`CONFIG_TOUCHSCREEN_GOODIX=y` (built-in — the rootfs `goodix.ko` is a 5.10 build
`CONFIG_TOUCHSCREEN_GOODIX=y` (built-in, the rootfs `goodix.ko` is a 5.10 build

Took 3 hardware-found fixes: rv1106 num_chans=1 (1 shared IRQ, not 4), CLK_CORE_MCU IGNORE_UNUSED (6.18 was gating the coprocessor clock), + an open SCR1 echo firmware with A2B_INTEN. The /dev/mem SRAM watchdog stays as a separate dead-man's-switch. |

GMAC -> trngv1 -> crypto-v3 -> OTP -> audio (codec/dsm) -> NPU -> mailbox -> pvtm.
GMAC + trngv1 first: highest real value (wired net + hardware entropy).
