fix(automation): honor the assignments wrapper shape on assignment nodes

[os-zhuang]

Problem

The built-in assignment node executor set each top-levelconfig key as a flow variable:

for(const[k,v]ofObject.entries(config))variables.set(k,v);

But every surface that authors these nodes emits an assignmentswrapper instead:

• Studio's visual Assignment editor → config: { assignments: { <var>: <value> } }
• bundled example flows (app-crm, showcase) → config: { assignments: [{ variable, value }] }

So a node designed in Studio (or any shipped example) silently set a single variable literally named assignments to the whole map/array and never set the intended variables — it passes build and no-ops at run time, leaving every downstream {var} reference unresolved. Classic "passes build / silent at runtime."

Found dogfooding the Studio Flow Builder as a business user.

Fix

builtin/logic-nodes.ts now normalizes all three shapes (assignments map, assignments array of {variable|name|key, value}, and the legacy flat { <var>: <value> }) and interpolates {var} templates in the values, matching the CRUD / screen nodes.

Tests

• New logic-nodes.test.ts covers each shape (map / array / flat / interpolation) as a regression guard — fails on the wrapper shapes before the fix.
• Full @objectstack/service-automation suite: 206 passing, no regressions.
