v0.7.0 - Context Management

[0.7.0] - 2026-03-07

Breaking

• Context: Context.budget removed. Use Context.token_limits (TokenLimits). ContextWindowBudget → ContextWindowCapacity. Context.get_budget(model) → Context.get_capacity(model). ContextManager.prepare() takes capacity instead of budget.

Added

• Context management — Snapshot (provenance, why_included, context_rot_risk), breakdown, custom compaction prompt, auto_compact_at, runtime injection, context_mode (full/focused), formation_mode (push/pull), stored output chunks, persistent context map, pluggable RelevanceScorer.
• Memory–context — Memory on by default; memory=None turns off. No extra field.
• Handoff/spawn — Context visibility in events (handoff_context, context_inherited, initial_context_tokens).

Fixed

• Examples: Output(type=...) → Output(MyModel); Agent(dependencies=...) → Agent(config=AgentConfig(dependencies=...)).
