Ruben Fiszel abc6b12d68 feat: WAC workflow diagram visualization via WASM (#8604)
* feat: WAC workflow diagram visualization in script editor

Add WASM-powered workflow diagram for WAC scripts in the script editor,
inspired by Cloudflare's workflow diagrams approach. Parses WAC code
client-side via WASM and renders an interactive DAG using @xyflow/svelte.

* feat: show WAC diagram on script detail page

Show the workflow diagram below the run form on the script detail page
for WAC scripts, matching how flows display their graph.

* feat: handle try/catch and while loops in WAC diagram

Instead of rejecting these patterns with validation errors, render them
as graph nodes:
- try/catch → Branch node with "try"/"catch" edge labels
- while loops → LoopStart/LoopEnd with condition as iter_source
