Collapses the load-test harness's chart-gen + helm-install dance into
first-class Harmony Scores. Customer-facing path:
let score = FleetServerScore::new(nats, operator);
score.create_interpret().execute(&Inventory::empty(), &topology).await?;
FleetOperatorScore renders the operator chart (CRDs + RBAC + ServiceAccount
+ Deployment) into a tempdir and delegates to HelmChartScore. FleetServerScore
composes it with NatsBasicScore via fail-fast `?` chaining; Zitadel + Argo
hang off the same chain when their Scores land.
Structural change: CRD type definitions and chart-builder moved from
fleet/harmony-fleet-operator/src/{crd,chart}.rs into
harmony/src/modules/fleet/operator/. Harmony can't depend on the operator
crate (cycle), so the score-side code lives in harmony and the operator
binary imports the types right back via
`harmony::modules::fleet::operator::*`. Considered keeping CRDs in the
operator crate with the score either there or in a sibling crate, but
putting customer-facing scores in harmony/src/modules/fleet/ matches the
existing convention (FleetDeviceSetupScore, ProvisionVmScore) and keeps
the CRDs reachable from future harmony scores (e.g. an inventory aggregator
reading Device CRs) without dragging in the operator binary.
The operator's `chart` subcommand stays as a developer convenience
(routes through harmony::modules::fleet::operator::build_chart) so
`cargo run -p harmony-fleet-operator -- chart` still produces an
identical chart on disk for inspection. Existing examples
(fleet_load_test, harmony_apply_deployment) updated to import CRD types
from harmony directly.
load-test.sh phase 3c collapses to a single
`cargo run -p example_fleet_server_install` invocation; phase 2b's NATS
install still runs separately so the host-side NATS reachability probe
sits where it always did. Idempotency: re-running short-circuits via
HelmChartScore::find_installed_release on both inner installs.
Verified: cargo fmt --check, cargo clippy, cargo test all pass; the
4 fleet operator unit tests (2 migrated from operator crate, 2 new on
FleetOperatorScore defaults/builders) pass under `cargo test -p harmony`;
operator chart subcommand produces an identical chart structure
post-refactor.
