.NET Compaction - Design Developer-Focused Compaction Pipeline Patterns

[crickman]

Define compaction pipeline patterns that emphasize developer usability, including sensible defaults and configurable parameters.

Prototype developer-friendly compaction presets (e.g., compact, balanced, maximum) and approaches (e.g., aggressive, balanced, gentle) based on conversation size limits and usage patterns.

Conduct a top-down analysis to assess supported scenarios, limitations, and performance impact.
