feat: kernel roadmap wave — bits4, policy v4, Pear/Bare compatibility

- protocol/booter: bits4 handshake, proc surfaces, boot policy v4, telemetry v4
- coreutils: nohup + ensure-man-pages; seed-man-pages fixes for extra pages
- kernel-runner: no static node:module (Pear); bare-module createRequire
- docs: handbook, reference, ADR, compatibility matrix, verify scripts
