Adds a `status` field to each target in build-graph.json and re-writes the file on every target state transition, so editor tooling watching it can animate a run live (queued → running → succeeded/failed) — the producer half of the live run graph. - BuildGraphUtility projects ExecutionStatus onto the graph control's vocabulary (scheduled→queued, running, succeeded, failed/aborted→failed, skipped). Neutral states (none/notrun/collective) emit null, so a structural or --plan snapshot stays unstyled and only a real run paints the nodes. - SerializeBuildGraphAttribute captures the targets at init and now also handles IOnTargetRunning/Succeeded/Failed/Skipped, re-emitting the graph (with the executor's in-place status updates) on each. Still best-effort — a write failure never fails the build; the write is locked. - Additive and backwards-compatible: a consumer that predates the field ignores the extra key, so it stays schema v1 (guarded by a test). Verified: unit tests cover the status projection; dogfooding `./build.ps1 Clean` emits build-graph.json with Clean=succeeded and the rest null.

The producer half of the live run graph:
build-graph.jsonnow carries per-targetstatusand is re-written on every target transition, so editor tooling (the VS Code extension) can watch the file and animate a run live — queued → running → succeeded/failed.BuildGraphUtilityprojectsExecutionStatusonto the control's vocabulary (scheduled→queued,running,succeeded,failed/aborted→failed,skipped). Neutral states (none/notrun/collective) emitnull, so a structural or--plansnapshot stays unstyled — only a real run paints the nodes.SerializeBuildGraphAttributecaptures the targets at init and now also implementsIOnTargetRunning/Succeeded/Failed/Skipped, re-emitting on each (the executor updatestarget.Statusin place before firing the hook). Best-effort, locked write — never fails the build.Additive / non-breaking: a consumer predating the field ignores the extra key, so it stays schema v1 (guarded by a test).
Verified: unit tests cover the status projection (

mountLive+ the extension's file-watcher) animates this automatically.
