📝 WalkthroughWalkthroughThe English protocol documentation now covers task dispatch and scheduling decisions. It defines scheduler-to-device-plugin communication through Pod annotations, GPU allocation metadata, updated registration timing, and a 3000 MiB allocation example. ChangesTask dispatch protocol documentation
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to This documentation adds the scheduler-to-device-plugin dispatch lifecycle and allocation examples. An unresolved concern about which Kubernetes component performs allocation could mislead implementers, so clarification is needed before merge. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

docs/developers/protocol.md lines 52-54 and
versioned_docs/version-v2.9.0/developers/protocol.md lines 52-54 to match
concept.md: document incremental removal from hami.io/vgpu-devices-to-allocate
after each successful mount, its empty state after all devices are allocated,
Unix bind-time timeout detection, and retention of
hami.io/vgpu-devices-allocated.
- Around line 44-46: Update the protocol description to state that kubelet calls
the device plugin’s Allocate method and passes its response to the container
runtime; remove the claim that kube-scheduler mounts the device. Apply the same
correction in docs/developers/protocol.md lines 44-46 and
versioned_docs/version-v2.9.0/developers/protocol.md lines 44-46.

/lgtm all five annotations are listed now with bind-phase named as the completion signal and both example states shown, and #812 turned out to be a changelog release rather than a docs snapshot so there is no v2.10.0 copy to sync. |

What type of PR is this?
/kind documentation
What this PR does / why we need it:
in docs/developers/protocol.md only the first half of the protocol lifecycle (Device Registration) was documented in English. The second half Task Dispatch & Scheduling Decisions was missing.
This PR ports and translates the second section from the Chinese documentation into English along with the existing architectural diagram task-dispatch.png resolving the known protocol diagram discrepancy mentioned in docs/diagrams-inventory.md (lines 244–250)
