Wiki Companion for OpenProject troch coxiplatypus

Wiki Companion for OpenProject improves the OpenProject wiki sidebar experience by applying predictable, non-destructive table of contents (TOC) auto-collapse behavior.

Main features:
- Auto-collapses non-active wiki branches to reduce clutter.
- Always keeps the currently active page branch open.
- Configurable global "Wiki tree keep-open depth" (default: 2).
- Per-site allowlist and per-site wiki toggle.
- One-shot apply per navigation/refresh, so manual branch expansions are respected during the current page session.
- Safe diagnostics notice if OpenProject selectors change.

Privacy and safety:
- No telemetry.
- No remote code execution.
- Uses optional host permissions only after explicit user action.
- Not affiliated with the OpenProject Foundation.
