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.
Expose the daemon request surface over /v1 with Axum, reuse shared key
parsing between CLI and HTTP, and add an isolated end-to-end HTTP test
that boots a real daemon process with temp XDG paths.
