Dolphie

- `Graph Metrics` panel switches are now properly updated when switching between host tabs

- Updated to the latest Textual version, which introduced significant changes to its core CSS. While working on the update, Dolphie's CSS was also cleaned up for improved readability and maintainability
- Disk I/O metrics are now displayed and recorded as part of `System Utilization`
- All system-related graph tabs have been consolidated into a single `System` tab
- Resolved issues 78 and 79
- Switching between host tabs is now smoother when the `Graph Metrics` panel is active

- Added new command `Z` to display table sizes & fragmentation ratio

- New panel! Pressing the `7` key now opens a panel displaying performance schema metrics from the `file_summary_by_instance` and `table_io_waits_summary_by_table` tables. Thanks to [ps-top](https://github.com/sjmudd/ps-top) for the inspiration!
- Uptime is now monitored as a global variable for replays, appearing in the `V` key view as a variable change when the server restarts
- Latency metric is now displayed during replays, showing the time Dolphie takes to execute queries per polling interval. This helps assess the host's performance
- Radio buttons and checkboxes are now visually more distinctive when selected

1. **Replay System Enhancements**

• A new progress bar now shows your position within a replay
• Dolphie now detects and logs global variable changes during recording while also notifying you when a variable’s value is modified. You can view all variables that changed in a replay with the new `V` command for quick reference

2. **Improved Recording Control in Tab Setup**

• A checkbox has been added to the `Tab Setup` modal, allowing you to easily enable or disable recording mode. This provides flexibility beyond the command-line-only `--record` option

3. **Enhanced Replay File Handling**

• Dolphie now provides clear error notifications if there’s an issue loading the replay file instead of crashing

4. **Code Quality and Bug Fixes**

• Various parts of the codebase have been refactored and cleaned up
• Several minor bugs have been addressed to improve overall stability and user experience

**Checkout the new progress bar!**
