## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
SubMiner visible overlay is slightly below mpv when mpv is fullscreen on Linux Hyprland. Align overlay bounds with mpv fullscreen client/monitor bounds.
<!-- SECTION:DESCRIPTION:END -->

## Acceptance Criteria
<!-- AC:BEGIN -->
- [x] #1 Hyprland fullscreen mpv overlay uses top-aligned geometry instead of inheriting a downward offset.
- [x] #2 Regression coverage captures the fullscreen Hyprland geometry case.
- [x] #3 Targeted tests pass.
<!-- AC:END -->

## Implementation Notes

<!-- SECTION:NOTES:BEGIN -->
Added follow-up Hyprland placement handling after the fullscreenClient geometry fix. SubMiner overlay/stats windows now get stable titles and, on Hyprland, are resolved from `hyprctl -j clients` by current PID/title, then set floating and pinned before bounds are applied. The stats overlay reapplies bounds after showing because Hyprland cannot see the hidden window before it is mapped.
<!-- SECTION:NOTES:END -->

## Final Summary

<!-- SECTION:FINAL_SUMMARY:BEGIN -->
Summary:
- Treated Hyprland `fullscreenClient` as a fullscreen signal when resolving mpv overlay geometry.
- Added Hyprland window placement handling so SubMiner overlay/stats windows are set floating and pinned before bounds are applied.
- Gave overlay/stats windows stable titles for Hyprland client matching, and reapplied stats bounds after show.
- Added regression coverage for the 28px fullscreen geometry shape and Hyprland placement dispatches.
- Added a changelog fragment for the overlay fix.
