* Harden session persistence: config storage, interrupted repair, prune tests Session config persistence: - Add session_config table to SQLite schema for persisting LLM-affecting parameters (temperature, reasoning_effort, max_tokens, instructions, creative_mode) across resume - Add save_session_config() and load_session_config() to memory.py - ChatSession._save_config() called on init and when /instructions, /effort, /creative slash commands change config - resume_session() restores persisted config and rebuilds system messages Interrupted session repair: - load_session_messages() now strips trailing incomplete tool call turns where tool_calls exist but fewer tool results than expected (session was interrupted mid-execution via Ctrl+C or crash) Cleanup: - delete_session() now also removes session_config rows - 14 new tests: interrupted repair (4), config persistence (5), prune_sessions (5) Docs & diagrams: - Document config persistence and interrupted repair in architecture.md - Add _save_config() to ChatSession in 03-core-engine-classes.puml * Fix Copilot PR #4 review: prune config cleanup, /new config persist, resume instructions - prune_sessions() now deletes session_config rows for orphaned/stale sessions - /new command calls _save_config() so config persists immediately - resume_session() uses key presence check for instructions, fixing cross-session leak - Add test_prune_removes_session_config covering both orphan and stale paths
