Session paths split by casing on case-insensitive macOS volumes

Description

On the default case-insensitive macOS filesystem, the same directory can be opened with different component casing. realPath preserves the caller spelling, so OpenCode stores separate Location keys and exact directory filters can hide existing sessions.

Steps to reproduce

1. Create /tmp/Academic/Project on a case-insensitive APFS volume.
2. Create a session using /tmp/academic/project.
3. List sessions using /tmp/Academic/Project.
4. The created session is missing because the stored path uses the caller casing.
