feat(packages/sui-lint): fix RepositoryLinter node_modules ignore for pnpm

[tomasmax]

Summary

• Fix fast-glob ignore pattern in RepositoryLinter/Runner.js to properly exclude node_modules in pnpm-managed repos
• Fix EISDIR crash in Match.js when directories have file-like extensions (e.g. Cypress screenshot dirs named *.js)

Problem

OOM crash (Runner.js)

sui-lint repository OOMs (crashes at 2GB heap) when running in repositories that use pnpm as package manager.

Root cause: fast-glob@3 treats the pattern 'node_modules' as matching only the literal top-level entry. It does NOT recursively prevent traversal into node_modules/.pnpm/ — pnpm's store directory that contains thousands of symlinked packages. The glob **/*.(j|t)s(x)? then matches files deep inside .pnpm/, reading all of them into memory until the process runs out of heap.

With the corrected pattern '**/node_modules/**', fast-glob skips any directory named node_modules at any depth.

EISDIR crash (Match.js)

Cypress creates screenshot directories named like .js files (e.g. cypress/screenshots/PTA/CategoryPicker.js). Match.create only checked isDirectory() when the path had no file extension, so these directories fell through to fs.readFileSync() which throws EISDIR.

Fix: Always check isDirectory() regardless of extension. Directory matches get raw = '' (empty string) instead of undefined, so rules that access match.raw.match(...) don't crash with a TypeError.

Results

Metric	Before	After
Execution time	OOM crash (exit 134)	~3.8 seconds
Memory	>4GB (exceeds heap limit)	~50MB
EISDIR errors	Crash on repos with Cypress screenshots	None

Tested on frontend-ma--web-app (pnpm 11, shamefully-hoist=true, ~10k source files).

Test plan

• Run sui-lint repository on a pnpm monorepo — completes without OOM
• Run sui-lint repository on a repo with Cypress screenshot directories — no EISDIR crash
• Run sui-lint repository on an npm monorepo — verify same behavior as before (no regression)
