bwcli serve: root / should serve index.html when it exists

[deftio]

Description

bwcli serve . intercepts the root / route with its own shell page (bitwrench chrome with injected scripts) even when an index.html exists in the served directory.

Expected: If the served directory contains an index.html, requesting / should serve that file (like any standard static file server — nginx, Apache, npx serve, GitHub Pages, etc.).

Actual: / returns the bwcli shell page. The file is only accessible via the explicit path /index.html.

Repro

echo '<h1>Hello</h1>' > /tmp/test-dir/index.html
npx bwcli serve /tmp/test-dir -p 8080
curl http://localhost:8080/       # => bwcli shell page
curl http://localhost:8080/index.html  # => <h1>Hello</h1>

Subdirectories work correctly — /site/ serves site/index.html as expected. The issue is only with the root /.

Notes

• --no-dir-list disables directory listings but does not change the root / behavior.
• This is bwcli serve v2.0.31.
