* Add es-metadata.yml (#1641)

* Fix INFO all/default/everything returning empty response (#1645)

* Fix INFO all/default/everything returning empty response

Implement support for INFO all, default, and everything options:
- all: returns all DefaultInfo sections excluding module-generated ones
- default: returns the default set of sections (same as no-arg INFO)
- everything: returns all DefaultInfo sections including modules

Added pre-declared HashSet collections (AllInfoSet, EverythingInfoSet)
in GarnetInfoMetrics.cs derived from DefaultInfo to support these options.

Updated InfoCommand.cs to use UnionWith with the new HashSets instead of
silently skipping the ALL keyword.

Added tests for all three options, verifying correct section inclusion/exclusion.

Fixes #1643

* make everything option use DefaultInfo

* Add null/empty guard in GetSectionHeaders test helper

Adds explicit asserts before splitting INFO output so test failures
surface a clear message instead of a NullReferenceException.

* Fix revivification CLI flag ordering dependency (#1644)

The validation in Options.GetServerOptions() checked the raw
enableRevivification flag (from --reviv) instead of the computed
useRevivBinsPowerOf2 state. This caused specifying --reviv alongside
explicit --reviv-bin-record-sizes and --reviv-bin-record-counts to
always fail, despite the --reviv help text documenting that it can be
overridden by the combination of these flags.

Changed the check from enableRevivification to useRevivBinsPowerOf2,
which correctly reflects that --reviv-bin-record-sizes already
overrides the power-of-2 default when present.

* Bugfix: Accept Loop socket error handling (#1646)

* Bugfix Accept Loop

* race condition and tiny loggin fix

* Dispose potentially partial sockets.

* Fix accept loop zombie state: tiered error handling with backoff retry

The accept loop in GarnetServerTcp.HandleNewConnection previously treated
all SocketError != Success as fatal, disposing the SocketAsyncEventArgs and
permanently killing the accept loop. This left the server in a zombie state
where existing connections worked but no new connections were accepted.

Changes:
- Extract HandleAcceptError with three-tier error categorization:
  - Tier 1 (fatal): OperationAborted, NotSocket, etc. — stop loop
  - Tier 2 (resource pressure): TooManyOpenSockets, NoBufferSpaceAvailable,
    etc. — backoff via Timer and retry (100ms initial, 5s cap)
  - Tier 3 (client-caused transient): ConnectionReset, etc. — log and continue
- Add ScheduleAcceptRetry using Timer to avoid blocking IOCP threads
- Dispose retry timer on server shutdown
- Add AcceptLoopTests with RST flood and extended attack simulation

* Handle SocketException on accepted socket configuration (#1648)

When a client RSTs between accept completing and socket setup (e.g. NoDelay),
the SocketException was unhandled and crashed the process. Wrap the post-accept
socket configuration in a try/catch, dispose the dead socket, and continue
the accept loop.

* Fix CLUSTER NODES and CLUSTER SHARDS metadata output (#1657)

* Fix CLUSTER NODES and CLUSTER SHARDS metadata output (#1650)

- CLUSTER NODES: Only append ,hostname when hostname is non-empty
- CLUSTER SHARDS: Replace 'address' field with Redis-compatible 'ip',
  'endpoint', and optional 'hostname' fields
- CLUSTER SHARDS: Honor ClusterPreferredEndpointType for endpoint field
  (ip address when Ip, hostname when Hostname)
- CLUSTER SHARDS: Fix role output to use 'master'/'slave' instead of
  enum names 'PRIMARY'/'REPLICA'
- Update NodeInfo struct and ClusterShards parser in test utilities
  for dynamic key-value field parsing
- Add ClusterShardsTest and ClusterNodesHostnameTest unit tests

* Refactor CLUSTER SLOTS/SHARDS to use StringBuilder

Replace string concatenation with StringBuilder in GetShardsInfo,
GetSlotsInfo, and their helper methods (AppendFormattedSlotInfo,
AppendNodeNetworkingInfo) to reduce intermediate string allocations.

* Address PR review comments and fix endpoint validation

- Fix endpoint validation (Options.cs): allow cluster-announce-ip when
  bind address is 0.0.0.0/:: (wildcard), since the server listens on
  all interfaces. Only require port match in that case.
- Handle ClusterPreferredEndpointType.Unknown in CLUSTER SHARDS: set
  endpoint to '?' consistent with CLUSTER SLOTS and redirects.
- Add ClusterShardsTest cases for Unknown endpoint type.
- Improve ClusterNodesHostnameTest to handle both hostname-present
  and hostname-absent branches.
- Add even-length guard and explicit role validation in ClusterShards
  test parser.
