ghr-cli 0.7.6

ghr v0.7.2 smooths the return path through details-heavy workflows: themes are now configurable, recent items avoid sending you back to the page you are already viewing, and PR/issue details restore their position more consistently across Inbox, repo views, list movement, and recent-item jumps.

Highlights:

- Added light and dark themes, persisted in config, with a command palette action to toggle the active theme.
- Recent items now keep a larger history, exclude the currently focused PR or issue from suggestions, and can include linked Inbox notifications.
- PR and issue conversation details now restore their last scroll/comment position whenever the same item is rendered again.
- The same PR or issue now shares a details-position identity across Inbox notifications, repo-scoped PR/issue views, and recent-item navigation, even when their internal WorkItem ids differ.
- Release docs and pinned install examples now point at v0.7.2.
