main ← subfolder
merged 11:18PM - 11 May 26 UTC
Preserve the path component when normalizing `--site` and `auth_pairs`
site URLs… so installations served from a subfolder (e.g.
`https://example.com/forum`) route correctly.
- Route leading-slash API paths like `/about.json` and `/search.json`
under the configured subfolder base
- Keep root-site behavior unchanged for sites hosted at the domain root
- Add tests covering subfolder and root-base URL resolution, cache key
stability, and the select-site/tethered search flows
Bumps version to 0.2.8.
