Add the static HTTP dashboard example and wire in the recent daemon/API polish:
CORS-aware API routing, service-install behavior cleanup, safer systemd unit
ExecStart quoting, and friendly-name validation for path-safe targeting.
Also refresh README/API/roadmap docs, remove the temporary claude observations
file, and include the related tests for API/status and daemon validation.
Switch API execution to direct daemon request handling, add regression
coverage for non-socket HTTP dispatch, and include the remaining pending
local updates across CLI/daemon/docs from the current worktree.
Reduce repeated adapter dispatch, CLI action rendering, and config save
flows while keeping the current Roku behavior and docs aligned with the
known secret-menu limitations.
Finish the Milestone 4 CLI surface with config management, daemon
install and uninstall helpers, config reload handling, and final
polish for secret redaction and running-socket tracking.
