* perf(studio): upgrade to Vite 8 + auto-install bun for 3x faster frontend builds
* fix(studio): make bun-to-npm fallback actually reachable
setup.sh used run_quiet() for the bun install attempt, but run_quiet
calls exit on failure. This killed the script before the npm fallback
could run, making the "falling back to npm" branch dead code.
Replace the run_quiet call with a direct bun invocation that captures
output to a temp file (same pattern, but returns instead of exiting).
Also clean up partial node_modules left by a failed bun install before
falling back to npm, in both setup.sh and build.sh. Without this, npm
inherits a corrupted node_modules tree from the failed bun run.
* fix(studio): restore commonjsOptions for dagre CJS interop
The previous commit removed build.commonjsOptions, assuming Vite 8's
Rolldown handles CJS natively. While optimizeDeps.include covers the
dev server (pre-bundling), it does NOT apply to production builds.
The resolve.alias still points @dagrejs/dagre to its .cjs.js entry,
so without commonjsOptions the production bundle fails to resolve
the CJS default export. This causes "TypeError: e is not a function"
on /chat after build (while dev mode works fine).
Restore the original commonjsOptions block to fix production builds.
* fix(studio): use motion/react instead of legacy framer-motion import
* fix(studio): address PR review findings for Vite 8 + bun upgrade
Fixes:
- Remove bun.lock from repo and add to .gitignore (npm is source of truth)
- Use & bun install *> $null pattern in setup.ps1 for reliable $LASTEXITCODE
- Add Remove-Item node_modules before npm fallback in setup.ps1
- Print bun install failure log in setup.sh before discarding
- Add Refresh-Environment after npm install -g bun in setup.ps1
- Tighten Node version check to ^20.19.0 || >=22.12.0 (Vite 8 requirement)
- Add engines field to package.json
- Use string comparison for _install_ok in build.sh
- Remove explicit framer-motion ^11.18.2 from package.json (motion pulls
framer-motion ^12.38.0 as its own dependency — the old pin caused a
version conflict)
* Fix Colab Node bypass and bun.lock stale-build trigger
Gate the Colab Node shortcut on NODE_OK=true so Colab
environments with a Node version too old for Vite 8 fall
through to the nvm install path instead of silently proceeding.
Exclude bun.lock from the stale-build probe in both setup.sh
and setup.ps1 so it does not force unnecessary frontend rebuilds
on every run.
