TooltipExtraData

## [1.4.1] - 2026-04-30

### Fixed
- Fixed a critical taint error caused by comparing tooltip text (GetText()) against addon-generated strings in TooltipHasLine.
- Fixed a taint-related error triggered by comparing secret/tainted unit name strings returned by UnitFullName.
- Fixed repeated errors: attempt to compare local 'existing' (a secret string value) in player tooltip handling.
- Fixed repeated errors: attempt to compare local 'name' (a secret string value) in inspect key generation.

### Changed
- Reworked player tooltip deduplication logic to rely exclusively on internal tooltip state instead of scanning and comparing tooltip text.
- Replaced inspect cache key generation from UnitFullName to UnitGUID for safer and taint-free identification.
- Simplified inspect queue validation by removing unnecessary unit string comparisons.

### Improved
- Increased overall stability of the playerinfo module when interacting with secure/tainted tooltip data.
- Reduced risk of UI taint propagation when hovering player tooltips repeatedly.
- Improved compatibility with Blizzard's protected tooltip system in Retail.
