[Repo Assist] feat(device): enhance device.status with os/cpu/memory/disk sections and sections filter

[github-actions]

🤖 This is an automated PR from Repo Assist.

Implements the structured sections proposed in #240, adding os, cpu, memory, and disk.drives fields to device.status plus a sections[] filter argument. All legacy fields are preserved for backward compatibility.

Changes

src/OpenClaw.Shared/Capabilities/DeviceCapability.cs

New field	Source	Notes
collectedAt	DateTime.UtcNow	ISO-8601 UTC timestamp
os.version	Environment.OSVersion.Version	e.g. "10.0.26100"
os.architecture	RuntimeInformation.OSArchitecture	e.g. "X64", "Arm64"
os.machineName	Environment.MachineName
os.uptimeSeconds	Environment.TickCount64 / 1000
cpu.name	PROCESSOR_IDENTIFIER env var / arch fallback	Existing GetModelIdentifier()
cpu.logicalProcessors	Environment.ProcessorCount
cpu.usagePercent	null	Reserved for platform-specific injection (e.g. PerformanceCounter)
memory.totalBytes	GC.GetGCMemoryInfo().TotalAvailableMemoryBytes	Physical RAM on Windows/Linux
memory.availableBytes	total - load
memory.usagePercent	Computed
disk.drives[]	DriveInfo.GetDrives()	All ready drives; each has name, label, totalBytes, freeBytes, usagePercent, format

sections parameter: if omitted, all sections are populated (backward-compatible). If provided (e.g. {"sections":["os","cpu"]}), only named sections are included and non-named sections are returned as null. Unknown section names return an error listing valid values.

Legacy fields (battery, thermal, storage, network, uptimeSeconds) remain unchanged.

tests/OpenClaw.Shared.Tests/CapabilityTests.cs

Three new tests added to DeviceCapabilityTests:

• DeviceStatus_ReturnsEnhancedSections — asserts collectedAt, os, cpu, memory, disk.drives are present and well-formed
• DeviceStatus_SectionsFilter_ReturnsOnlyRequestedSections — asserts non-requested sections are null
• DeviceStatus_SectionsFilter_RejectsUnknownSections — asserts error response for unknown section names

Test Status

Suite	Result
OpenClaw.Shared.Tests (new DeviceCapability tests)	✅ 3 new tests passing
OpenClaw.Shared.Tests (full suite)	✅ 967 passed, 20 skipped; 3 pre-existing McpHttpServerTests failures unrelated to this change (see PR #238)
OpenClaw.Tray.Tests	✅ 202 passed, 0 failed

🤖 Repo Assist note: This PR is superseded by community PR #249 ("feat(device): enhance device.status with rich system health sections...") by @RBrid, which implements the same feature with a more comprehensive design — including an IDeviceStatusProvider injection pattern, per-section fault tolerance via SafeCollect wrappers, WinRT battery + P/Invoke memory + PerformanceCounter CPU sampling, and 18 new tests. Since #249 already addresses issue #240 with a better architecture, this Repo Assist PR should be closed in favour of #249. @shanselman please close when convenient.

Closing per repo-assist triage: this is superseded by the broader provider-based device status work in #249, and this draft leaves important semantics/provider gaps unresolved.
