v0.7.0

Breaking changes

• Remove the deprecated @grundyjs/algiviz/core entry point and bundled insertion/bubble algorithms.
• Use application-owned algorithms with /array; array playback adapters now live in /array.

Fixes

• Preserve source step indices in generic timeline frames, matching generator playback.
• Preserve primary playback errors when iterator cleanup also fails; standalone cleanup failures still propagate.

Validation

• 69 tests and the isolated packed-package consumer passed.
• CI passed for 4a8c4b1.
• grundyjs.ru compatibility verified with Next.js 16.3.0: algorithm/video checks, lint, production build, and browser playback checks.
