Full Release Notes

## Bug Fixes
- prevent last char truncation in TextPath when path length equals text width [#2032](https://github.com/konvajs/konva/pull/2032) ([copilot-swe-agent[bot]](https://github.com/konvajs/konva/commit/b2f58e710052dd405f893a5930acf7b2ae109ade))
- **TextPath**: use kerning measurement diff as dynamic threshold instead of static epsilon [#2032](https://github.com/konvajs/konva/pull/2032) ([copilot-swe-agent[bot]](https://github.com/konvajs/konva/commit/517d6517c04592dc54d02316602138909efcf17d))

## Code Refactoring
- extract GLYPH_PATH_PRECISION constant for the epsilon threshold [#2032](https://github.com/konvajs/konva/pull/2032) ([copilot-swe-agent[bot]](https://github.com/konvajs/konva/commit/ad3ebd61caad96ca556aa29e59ba02cd8e94b70e))

## Tests
- **TextPath**: add ±1px tolerance to width assertion in 'check bad calculations 2' [#2032](https://github.com/konvajs/konva/pull/2032) ([copilot-swe-agent[bot]](https://github.com/konvajs/konva/commit/53308b88c0d80b78bf3d6c1bcbe6de588d2290b3))
