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.
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.
