> [!NOTE]
> **Medium Risk**
> Medium risk due to broad Rust/Node toolchain dependency upgrades (notably `oxc`/resolver/minifier and `rolldown` plugin set changes) that can affect build/bundling output and platform-specific behavior.
> 
> **Overview**
> Upgrades a large set of upstream dependencies across the Rust workspace and pnpm monorepo, including `oxc` `0.114.0` → `0.115.0`, `oxc_resolver` `11.18.x` → `11.19.0`, `jsonschema` `0.38.x` → `0.42.x`, `flate2` `1.1.5` → `1.1.9`, `ts-rs` `11` → `12`, and `sugar_path` `1.x` → `2.x` (with corresponding `Cargo.lock` churn and Windows/socket transitive bumps).
> 
> Updates bundled/tooling versions and upstream pins (`packages/core` now bundles `vite` `8.0.0-beta.16` and `rolldown` `1.0.0-rc.6`, `.upstream-versions.json` hashes updated), and refreshes `pnpm-lock.yaml` with associated ecosystem bumps (e.g., `@types/node` `24.10.15`, `minimatch` `10.2.4`, ESLint/TypeScript-ESLint updates).
> 
> Adjusts project integration points: replaces `rolldown_plugin_data_uri` with `rolldown_plugin_copy_module` and `rolldown_plugin_data_url`, adds a pnpm `packageExtensions` entry for `@rollup/plugin-dynamic-import-vars` (`@types/estree`), drops the `http-proxy-3` patch, and updates the CLI `snap-test-global` `--bin-dir` path.
