feat(P10b): drift detection (R-018/R-019/R-020, REQ-103..113)

internal/drift/drift.go: Detector (Watch via iter.Seq2, Aggregate,
Remediate with cooldown-on-success, Acknowledge), Config with tiered
cadence (critical 5s + Path units, standard 30s, default 60s).
internal/cli/drift.go: orca drift {show,watch,acknowledge,remediate,
config}. internal/emitter/drift_path.go: systemd Path+service unit
emitter (User=orca, ProtectSystem=strict). scripts/orca-drift-notify.sh
(sha256 event JSON), orca-remediate.sh (cooldown-on-success, transient
retry). Pre-flight gate (R-020, --force + per-ns scoping). orca
system user (REQ-111), NFS detection (D-233), orca job restart for
EnvironmentFile drift (D-235).
