1. Add Client.SendHeartbeat/Register methods — no more direct postJSON calls
2. Use url.Values for query params to prevent URL injection
3. Unexport helpers (envOrDefault, durationFromEnv, sleepWithContext)
4. CLI resolveWorkspaceID falls back to daemon.json
5. Implement agent stop (PUT /api/agents/{id} with status=offline)
6. Add --output flag to agent get for consistent UX
7. Add server/multica to .gitignore for stray builds
8. Inject version/commit via -ldflags in Makefile build target

Extract daemon logic from cmd/daemon/ into internal/daemon/ package and
create a new unified CLI entry point at cmd/multica/ using cobra. The CLI
supports `daemon` as a long-running subcommand plus ctrl subcommands for
agent/runtime management, config, status, and version.
Server, migrate, and seed binaries remain unchanged.
