Implement repository-based firmware update for Lenovo Redfish BMC - #1214
Add FirmwareUpdaterLenovo (not part of the BMC union, like FirmwareUpdaterDell) for the XCC OEM repository update:
InstallFirmwareFromRepository: POST LenovoUpdateService.UpdateFromRepository with RepoURI; returns the task URI (body @odata.id, Location fallback, normalized to a TaskService path). Errors after the POST are fatal to avoid a second update.
GetRepositoryUpdateTask: polls the standard Redfish task via getUpgradeTask.
GetPendingFirmwareComponents: *-Pending FirmwareInventory slots with staged firmware (not Disabled, non-empty Version); BMC/XCC and UEFI slots are excluded since they are managed by the BMCVersion/BIOSVersion controllers.
GetRepositoryUpdateDetail: returns LenovoUpdateService.GetRepoUpdateDetail as-is (undocumented ret/BundleErrorCode codes are not interpreted).
Extend the mock server with the Lenovo update flow (opt-in via WithLenovoFirmwareInventory()), including staging and activation on host reset, and a component without a -Pending slot.
Unit tests, partly based on responses recorded on an SR650 V4 (XCC 28L-2.00).
Notes from testing on real hardware:
Components such as network adapters have no -Pending slot; their staged firmware only becomes visible in the FirmwareInventory after the host reboot.
GetRepoUpdateDetail reports the last run on the XCC (also runs started by LXCA); devices[].version is the version before the run, and ret: 2 was observed for successfully applied packages that need a reboot.
The orchestration (reboot handling, evaluating the result) will be implemented in metal-maintenance-operator.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Adds Lenovo Redfish methods for repository-based firmware updates and a mock-server simulation. The simulation provides task progress and update details. When inventory simulation is enabled, it stages firmware until host power-on or reset activates it.

Summary
Client update and response handling bmc/redfish_lenovo.go, bmc/redfish_lenovo_test.go
Adds methods to submit repository updates, retrieve tasks and update details, and list pending firmware components. Tests cover request handling, response parsing, task retrieval, and inventory filtering.
Mock task progression and update details bmc/mock/server/server.go, bmc/mock/server/data/TaskService/Tasks/lenovo-repo/*, bmc/mock/server/data/UpdateService/index.json, bmc/redfish_lenovo_test.go
Adds mock routing and task progression for successful and failed repository updates. Successful updates produce update details. Tests cover task states and invalid repositories.
Firmware inventory staging and activation bmc/mock/server/server.go, bmc/mock/server/data/UpdateService/FirmwareInventory/*, bmc/redfish_lenovo_test.go
Mock-based update workflows can intermittently observe incomplete results after task completion. The risk is confined to the mock server.

Full details: Title check
Explanation
The title states the main change: a repository-based firmware update for Lenovo Redfish BMC. The changeset adds FirmwareUpdaterLenovo with InstallFirmwareFromRepository, polling, pending-component listing, and detail retrieval, plus mock server support and tests. The title is specific and concise, and it matches the primary intent in the PR objectives.
Full details: Description check
Explanation
The description follows the template structure. It has the '# Proposed Changes' heading with bullet points detailing the added API methods, mock server extension, and unit tests. It also includes testing notes and scope context. The template's closing line 'Fixes #' is absent, and no linked issue number is given. The PR objectives reference PR #1214, which is a related PR, not an issue. This is a minor gap in a non-critical field, so the description is mostly complete.

Review comments at @bmc/redfish_lenovo.go:
- Line 320: Update InstallFirmwareFromRepository and GetRepositoryUpdateDetail
to bind their Lenovo POST requests to the caller’s operation context; also bind
the task GET in getUpgradeTask and nested job GET in lenovoParseTaskDetails to
that context. Use the client’s context-bound request path for each request so
all repository update calls honor the operation deadline.
- Around line 282-308: Update lenovoExtractRepositoryTaskURI to normalize both
@odata.id and Location values before returning them: convert absolute URLs to
their request path and query, and reject values whose path is outside the
Redfish TaskService endpoint. Preserve the existing body-first,
Location-fallback behavior.

Turn absolute task URIs from @odata.id or the Location header into their
path, since gofish prefixes every request with the BMC endpoint, and reject
URIs outside the Redfish TaskService.

Use the existing lenovoExtractTaskMonitorURI function for all three
use cases (BIOS SimpleUpdate, BMC SimpleUpdate, and Repository
UpdateFromRepository) instead of maintaining a separate
lenovoExtractRepositoryTaskURI function.
The Lenovo XCC always provides @odata.id in the response body for
both SimpleUpdate and UpdateFromRepository operations, returning
relative paths that Gofish automatically prefixes with the BMC
endpoint. No normalization is needed.
Removed functions:
- lenovoExtractRepositoryTaskURI
- lenovoNormalizeTaskURI
Removed constants and imports:
- lenovoTaskServicePathPrefix
- net/url, path
Updated tests to send response bodies with @odata.id instead of
Location headers, and fixed WriteHeader call order to properly
test HTTP 202 Accepted responses.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Restore the Location fallback for repository updates.
If XCC returns HTTP 202 with a Location task monitor but no @odata.id in the body, lenovoExtractTaskMonitorURI fails. InstallFirmwareFromRepository then reports a fatal error after the update may have started, and the caller receives no task URI to poll. Redfish permits a 202 response without a body and requires the task-monitor Location header. Keep body-first extraction, but use Location when the body supplies no task URI. (redfish.dmtf.org)
