fix: prevent file browser flashing and reduce log verbosity

- Split visibility and session change handling to avoid redundant directory loads
- Only reload directory when component becomes visible or session changes while visible
- Change directory browse success log from info to debug level to reduce noise
- Fixes issue where file browser would flash/reload unnecessarily on prop changes
```
