Module workbench 

v0.48: local workbench — axum web app rendering the substrate against the cwd’s .vela/ repo.

Doctrine: the static site (vela-site.fly.dev) is a marketing surface bundled against one frontier at build time. The workbench is a single-binary, single-user, localhost UI that renders the user’s frontier, with read+write actions that hit the same on-disk representation vela <subcommand> would.

Architecture:

• Pure Rust + axum. No node, no bun, no static-build step.
• Each request reads from disk. Writes call back into the same modules vela <cmd> uses (e.g., bridge confirm rewrites the .vela/bridges/<vbr_id>.json file in place).
• Shared CSS with the hub (web/styles/tokens.css, web/styles/workbench.css) via include_str!.
• Auto-opens the default browser on start unless --no-open.

Functions

run

Start the workbench on 127.0.0.1:<port>, against repo_path. If open_browser is true, opens the default browser at the local URL.
