Context

The previous version of the segmentation loader claimed to support labelmap, but didn't actually work for loading them. As well, both bitmap and labelmap supposedly had RLE support, but again it didn't quite work.
This change adds storing as either labelmap or bitmap, and allows storing in RLE. The RLE encoder is also fixed to support 1,8,16 bits, and actually does the RLE correctly instead of using a count of 1 for every pixel.

The result of this is far faster loading of seg images from standard back ends supporting the SEG frame retrieve rather than trying to retrieve the entire DICOM file. On storage, the store size is also significantly smaller as RLE compresses extremely well for segmentation images.

…eehandROI open U-shape contours (#2615)

* feat(tools): implement orthogonalT and lineSegment modes for PlanarFreehandROI open U-shape contours

Add two new rendering modes for the open U-shaped contour T-overlay:

- 'orthogonalT': computes the T-line endpoint as the perpendicular
  ray-contour intersection from the chord midpoint, instead of the
  farthest point. Useful for LA cardiac workflows where the T must be
  perpendicular to the chord.

- 'lineSegment': draws only the dashed chord connecting endpoints
  without any T-line, closing the contour visually.

Also adds optional shaded fill for the enclosed region (contour + chord)
when fillOpacity > 0, and centralizes variant dispatch into a single
resolveVectorToPeak function to eliminate duplicated branching across
drawLoop, openContourEditLoop, and renderMethods.

* fix(tools): address PR review for PlanarFreehandROI U-shape modes

- Use vec2.sub instead of create+set for chord vector
- Replace double-loop ray intersection with single-pass dot-product
  approach for orthogonalT peak finding
- Return null with console.warn instead of falling back to farthestT
  when no orthogonal intersection is found
- Add 'none' option to U-shape dropdown to remove U-shape rendering
- Auto-apply U-shape mode on dropdown change, remove separate button
- Apply configured U-shape mode to newly drawn open contours
- Add fill opacity dropdown using tool configuration
- Read fillOpacity from tool config in renderMethods

* refactor(tools): use vec2.dot for orthogonal T dot product calculation

* Move open u shaped to utils helper

* fix(security): Various dependency updates as a result of CVE-2026-26996.
Ultimately the vulnerability was ignored because it is only exposed in itk-wasm via CLI and it is limited to build/dev environments.
* refactor: update getTextBoxCoordsCanvas function to accept element and textLines parameters for improved textbox placement across multiple annotation tools

* fix: correct bounding box calculations in _drawTextGroup function to accurately reflect text box position and size

* feat: implement text box overlap management with registry for improved placement accuracy

- Added a text box overlap registry to track rendered text box positions.
- Integrated overlap avoidance logic in getTextBoxCoordsCanvas to prevent occlusion of existing text boxes.
- Updated draw and drawTextBox functions to clear and register text boxes during rendering.

* refactor: enhance overlap detection in getTextBoxCoordsCanvas using AABB intersection

- Replaced the previous rectangle overlap logic with a more accurate AABB intersection method.
- Introduced a new utility function to convert text box rectangles to AABB format, allowing for better handling of overlap checks.
- Updated the overlap detection functions to utilize the new intersection logic for improved accuracy in text box placement.

* test: add unit tests for getTextBoxCoordsCanvas to validate positioning logic

- Introduced a new test suite for getTextBoxCoordsCanvas to ensure correct coordinate calculations for text boxes.
- Added tests for default positioning, overlap handling, and fallback mechanisms when space is limited.
- Utilized a mock viewport element to simulate various scenarios for accurate testing.

* style: format getTextBoxCoordsCanvas test cases for improved readability

- Reformatted the test cases in getTextBoxCoordsCanvas.spec.ts to enhance code clarity.
- Adjusted the indentation and line breaks for better visual structure without altering functionality.

* refactor: update type assertions in getTextBoxCoordsCanvas tests for better type safety

- Changed type assertions from any to unknown in getTextBoxCoordsCanvas test cases to enhance type safety and maintain code quality.
- Ensured consistency in type handling across the test suite without altering existing functionality.

* refactor: remove unnecessary type assertions in getTextBoxCoordsCanvas tests

- Updated test cases in getTextBoxCoordsCanvas.spec.ts to eliminate type assertions from unknown to the actual type for annotationPoints and related variables.
- Improved code clarity and type safety without changing the existing functionality of the tests.

* chore: update tsconfig.json to exclude test files from compilation

- Added an "exclude" property to tsconfig.json to prevent test files from being included in the TypeScript compilation process.
- This change helps streamline the build process by omitting unnecessary test files.

* refactor: integrate getTextBoxCoordsCanvas into ArrowAnnotateTool for improved text box positioning

- Replaced direct canvas coordinate assignment with a call to getTextBoxCoordsCanvas to enhance the accuracy of text box placement.
- This change ensures that text box coordinates are calculated based on the current canvas state and element, improving overall annotation functionality.

* refactor: streamline text box rendering across annotation tools

- Replaced direct text box rendering logic with a unified renderLinkedTextBoxAnnotation method in multiple annotation tools.
- This change enhances code maintainability and consistency in text box visibility and positioning logic.
- Improved handling of text box state and coordinates, ensuring better integration with existing annotation functionalities.
