Module context 

Context window management — smart truncation and token counting.

This module provides:

• Token estimation (fast, no external deps)
• Tiered compaction (tool output truncation → turn summarization → full summary)
• Non-destructive compaction overlays (CompactionBlock on LoopRecord)
• Execution limits (max turns, tokens, duration)

Sub-modules:

• token — Token estimation functions
• config — ContextConfig, CompactionConfig, CompactionScope
• tracker — ContextTracker (hybrid real+estimated tracking)
• compaction — CompactionBlock, CompactedSection, TurnRange, TurnMap
• strategy — CompactionStrategy, BlockCompactionStrategy, DefaultBlockCompaction
• [compact_messages] — Legacy tiered compaction (level 1/2/3)
• execution — ExecutionLimits, ExecutionTracker
• orchestration — compact_session_loops, build_context_from_session
