feat(joint-router-avoid): new avoid router package

[Geliogabalus]

Summary

• Adds a new @joint/routers-avoid package integrating the libavoid routing library (main-thread and Web Worker providers) as a JointJS router.
• Adds an avoid-router example app demonstrating the router on a large sample graph.
• Minor fixes in rightAngle router and LinkView needed to support the new router.

Test plan

• yarn test passes for joint-routers-avoid package
• avoid-router example builds and runs (yarn ensure-examples-can-build)
• Manually verify routing behaves correctly with both main-thread and worker providers

Pull request overview

Adds libavoid-based orthogonal routing to JointJS via a new workspace package and demo, with supporting changes in @joint/core to share the rightAngle path algorithm and improve routing/anchor handling.

Changes:

• Introduces @joint/router-avoid with main-thread + Web Worker providers, plus Karma/QUnit end-to-end tests.
• Refactors rightAngle router to reuse a new exported alg.rightAnglePath() implementation and adjusts LinkView anchor usage.
• Adds an examples/avoid-router demo app and wires new workspace deps into the monorepo.

• flushMessageQueue is currently a const debounced with the module-level default debounceTime. To support debounceTime coming from init options, it needs to be re-creatable/reassignable.
