IsolatedCompactionStrategy

[Rexios80]

Closes #305

[Copilot]

Pull request overview

This PR addresses #305 by making compactionStrategy usable with IsolatedHive by replacing the non-sendable CompactionStrategy function parameter with a sendable IsolatedCompactionStrategy that can be serialized, transmitted across isolate boundaries, and rehydrated inside the Hive isolate.

Changes:

• Introduces IsolatedCompactionStrategy (JSON-serializable) with threshold(...) and never() options and rehydrates it in the Hive isolate handler.
• Updates IsolatedHive APIs and implementations (VM/web/stub) to accept IsolatedCompactionStrategy? instead of CompactionStrategy?.
• Adds build.yaml configuration and updates generated files to include consistent ignore_for_file directives.
