chore(secrets): 0.4.0 — ship ZB.MOM.WW.Secrets.Replicator.Grpc (pull-only central hub)

Bumps the ZB.MOM.WW.Secrets family from 0.3.0 to 0.4.0 and adds the new
ZB.MOM.WW.Secrets.Replicator.Grpc package to the packable set. Publishes
all six 0.4.0 nupkgs to the dohertj2-gitea feed and restore-verifies the
new package resolves from it in a fresh --packages directory. Existing
packages are behaviorally unchanged — no breaking changes.

Adds ZB.MOM.WW.Secrets/CHANGELOG.md (none existed previously) to record
this and prior releases, and lists the new package in README.md's
Packages table. Also includes the controller's pending ledger updates
for docs/plans/2026-08-07-secrets-grpc-hub-implementation.md (Tasks
1-4 and 8 marked completed).

# Changelog
All notable changes to the `ZB.MOM.WW.Secrets` family are recorded here. Format loosely
follows [Keep a Changelog](https://keepachangelog.com/); versions are shared across every
package in the family (see `Directory.Build.props`) even when a given release only touches
one of them.
## 0.4.0 — 2026-08-07
### Added
- **New package `ZB.MOM.WW.Secrets.Replicator.Grpc`** — a central-hosted `secrets_hub.v1`
gRPC hub for the sites-talk-to-central production topology (scadaproj#3; design doc
[`docs/plans/2026-08-07-secrets-production-topology-and-grpc-hub.md`](../docs/plans/2026-08-07-secrets-production-topology-and-grpc-hub.md)).
- **Pull-only by construction**: the proto exposes no write RPC. Updates originate at
central only; a site never pushes a secret upstream.
- **Fail-closed bearer auth** on the hub server: constant-time comparison, uniform denial
response (no signal distinguishing "wrong token" from "missing token"), a warn-once log
on an unconfigured/empty token rather than a silent open door.
- `GetSecrets` enforces a batch-size cap, rejecting an oversized request with
`ResourceExhausted` instead of serving it partially or unbounded.
- Site-side `GrpcSecretSyncService` sweeps the hub on an interval with **per-row parse
isolation** — one malformed/undecryptable row logs and is skipped, it does not fault the
whole sweep.
- Keyed `GrpcChannel` registration so multiple hub targets can be wired in one process
without channel collisions.
- **Offline behavior is last-known-good**: if the hub is unreachable, the site keeps
serving the most recently synced values rather than failing secret resolution.
### Unchanged
- `ZB.MOM.WW.Secrets.Abstractions`, `ZB.MOM.WW.Secrets`, `ZB.MOM.WW.Secrets.Ui`,
`ZB.MOM.WW.Secrets.Replicator.SqlServer`, and `ZB.MOM.WW.Secrets.Replicator.AkkaDotNet` are
behaviorally unchanged in this release — no breaking changes to any existing package.
## 0.3.0 — 2026-07-19
- Menu-driven Spectre.Console interactive operator console added to the `secret` CLI (list /
set / reveal / delete, reference audit & seed, KEK doctor, ciphertext-only bundle
export/import). See
[`docs/operations/interactive-console.md`](docs/operations/interactive-console.md).
## 0.2.3 — 2026-07-19
- `ZB.MOM.WW.Secrets.Ui`: fixed the delete-confirmation modal being permanently invisible on
every Bootstrap host (`ConfirmDeleteModal` used bare `class="modal"` with no shipped CSS;
Bootstrap's `.modal{display:none}` hid it everywhere but mxaccessgw). Fixed via a
`zb-secrets-modal*` class rename plus a component-emitted `<style>` block.
## 0.2.2 — 2026-07-18
- Fixed the Akka replicator's hosted-process DI deadlock (a circular singleton dependency
hidden behind factory lambdas that MS.DI's `StackGuard` turned into a silent cross-thread
hang rather than a stack overflow). New `DeferredSecretCacheInvalidator` defers the one
cycle-closing edge to first eviction.
## 0.2.1 — 2026-07-18
- Fixed the Akka replicator being silently inert since 0.2.0 (a `TryAdd` registration-order
bug published into a no-op sink and never spawned an actor). SQL-Server replication was
never affected.
## 0.2.0 — 2026-07-18
- Added clustered replication (G-7): `ZB.MOM.WW.Secrets.Replicator.SqlServer` (shared store,
or local-store-with-hub) and `ZB.MOM.WW.Secrets.Replicator.AkkaDotNet` (peer-to-peer over
distributed pub/sub).
