- docs-integrity: normalize walker paths to forward slashes so keys match on Windows
- export-git-e2e: run tsx's JS entry via node instead of the .bin/.cmd shim (same pattern as #63)
- vitest: 30s testTimeout for CPU-bound PNG-render tests on slower machines
(build.mjs portion of the original branch dropped — superseded by #63)
The original bug lived in collectSource's --git untracked branch, not in the
readExportTextFile helper the unit tests cover. Add an E2E test that runs the
actual CLI (tsx src/node.ts export --git --include '*.ts') against a throwaway
git repo with a tracked baseline plus untracked keep.ts, a 5000-char skip.md, an
oversized huge.ts, and a binary bin.ts. Asserts oversized + binary untracked
files are skipped (with warnings) and that only keep.ts's content reaches the
source (sourceChars < 500 — skip.md would have added thousands).
