fix(frontend): exclude nested node_modules from the vitest run

[codebanditssss]

Closes #216.

Problem

frontend/vite.renderer.config.ts set test.exclude to ["node_modules/**", ...]. Providing exclude replaces vitest's default **/node_modules/** (it doesn't merge), and the root-anchored node_modules/** doesn't match nested node_modules. src/landing is a tracked, self-contained Next.js preview app with its own deps, so once those are installed, npm test collected and ran vendored third-party suites (zod, next, react-medium-image-zoom, style-to-js) → 20+ failures from code that isn't ours.

Change

"node_modules/**" → "**/node_modules/**" so nested node_modules are excluded at any depth.

Test

• Before: npm test collected 185 files / 2033 tests with 8 failed files / 20 failed tests, all under src/landing/node_modules/**.
• After: npm test collects only the renderer's 10 files / 121 tests, all passing, with zero src/landing/node_modules references — and runs in ~6s instead of ~50s.

Greptile Summary

Fixes a vitest misconfiguration where the test exclude list used a root-anchored node_modules/** glob that silently failed to exclude the nested node_modules trees brought in by the tracked src/landing Next.js preview app, causing 185 vendored third-party test files to be collected and 20+ to fail.

• Replaces \"node_modules/**\" with \"**/node_modules/**\" in test.exclude, matching the pattern vitest uses in its own default — this is the correct fix for nested node_modules at any directory depth.
• The remaining entries (dist/**, dist-electron/**, e2e/**) remain root-anchored; these only exist at the project root today, but they would need the same treatment if subdirectories ever contain their own dist or e2e folders.

Confidence Score: 5/5

Safe to merge — single-line glob fix in test config with no impact on build or runtime behaviour.

The change is a one-line correction to a glob pattern in the vitest exclude list. It aligns the project's explicit pattern with vitest's own default, is fully explained in the added comment and PR description, and the before/after test counts confirm the intended effect.

No files require special attention.

Important Files Changed

Filename	Overview
frontend/vite.renderer.config.ts	Changed test.exclude pattern from root-anchored "node_modules/" to depth-agnostic "/node_modules/**" so vendored suites inside src/landing/node_modules are no longer collected by vitest.
