Add table-driven rootCmd.Execute() tests for the node, job, cert,
doctor, audit, status, version, and node-capacity subcommand families.
Each test runs against a temp ORCA_HOME and asserts stdout/stderr/exit
via the existing initTestEnv/resetRootFlags/discardWriter helpers
(RESEARCH §1.2). extend resetRootFlags to also reset the per-command
flag-bound globals so tests don't leak state between runs.
daemon.go is excluded from the ≥70% target (documented in node_test.go):
the daemon command starts a long-running mTLS server whose lifecycle is
covered by internal/daemon/server_test.go; only its --pprof flag
registration is verified here (daemon_test.go).
Coverage: go test -cover ./internal/cli → 76.2% overall (78.7% by
-func), which includes daemon.go's untested RunE; the non-daemon files
exceed 70% comfortably. go test -race PASS.
