feat(session-anchors): configurable budget scale + research-backed truncation fix

Browse source 
Remove 500-char assistant text truncation in anchor serializer — research
consensus (JetBrains NeurIPS 2025, SWE-agent, OpenDev ACC) is that agent
reasoning must never be truncated; only tool outputs get observation-masked.

Add AnchorBudgetScale type with 4 presets (Small=2K, Medium=6K, Large=12K,
Full=20K) and per-project range slider in SettingsTab. Remove Ollama-specific
warning toast — budget slider handles context limits generically.
