fix(spec): make GanttConfigSchema forward-compatible via .passthrough()

The gantt renderer (objectui plugin-gantt) keeps adding view-config knobs
(lockField, defaultCollapsedDepth, ...) ahead of this schema. The console
validates the view config against a bundled copy of GanttConfigSchema before
handing it to the renderer, so any field not declared here is stripped --
every new renderer knob otherwise needs a spec release + console rebuild to
take effect. .passthrough() lets unknown fields reach the renderer, decoupling
renderer releases from spec releases. Known fields keep their validation.

Adds a forward-compat test asserting unknown fields survive parse.

+fix(spec): make `GanttConfigSchema` forward-compatible via `.passthrough()`.
+
+The gantt renderer (objectui plugin-gantt) keeps adding view-config knobs
+(e.g. `lockField`, `defaultCollapsedDepth`) ahead of this schema. Without
+passthrough, the console — which validates the view config against a bundled
+copy of this schema before handing it to the renderer — strips any field not
+declared here, so every new renderer knob needs a spec release + console
+rebuild before it can take effect. Adding `.passthrough()` lets unknown fields
+flow through to the renderer, decoupling renderer releases from spec releases.
+Known fields keep their validation; the renderer still only reads what it
+understands.
