Summary

• Adds a long-term conversation log (IConversationLog / FileConversationLog) that accumulates all conversation turns as JSONL
• Adds a new dream-sequence pass (RunPreferenceInferencePassAsync) that analyzes the log for durable user preference patterns and saves them as tagged inferred memory entries
• Log is always cleared after each pass to prevent unbounded growth
• Preference inference is opt-in via WithConversationLog() — existing agents are unaffected

New files

Modified files

• DreamOptions.cs — added PreferenceInferenceEnabled (default true) and PreferenceDirectivePath ("pref-dream.md")
• FileConversationMemory.cs — fire-and-forgets AppendAsync on every AddTurnAsync when log is wired in
• DreamService.cs — preference inference pass with sentiment-based thresholds, built-in directive, finally-guarded log clear
• AgentMemoryExtensions.cs — added WithConversationLog() explicit opt-in extension

Usage

builder.WithMemory();
builder.WithConversationLog();   // opt-in
builder.WithDreaming();

Test plan

• dotnet build RockBot.slnx — clean build, 0 errors
• dotnet test RockBot.slnx — all 539 tests pass, 0 failures
• 7 new FileConversationLogTests all pass (round-trip, clear, concurrent appends, missing file)
