ci: GHA→ghcr builds for chrome-service-novnc, android-emulator, infra CLI (ADR-0002 #29/#30)

Infra-owned rare-build images move off Woodpecker/manual to GHA (build
from the github checkout — Dockerfiles verified identical on both
remotes). chrome-service-novnc + android-emulator → public ghcr
(dispatch+path). CLI → DockerHub (kept) + ghcr; Woodpecker build-cli.yml
removed. infra-ci handled separately (bootstrap-critical).
