Pull request overview

This PR refactors Phrase Memory to move away from preset-based splitting toward a workspace-scoped LLM “memory extractor” (provider/model/prompt), adds confidence metadata to saved matches, and updates pipeline/search configuration to explicit search controls.

Changes:

• Replace Phrase Memory presets/splitters with a workspace “memory extractor” (plus new memory prompt-template context).
• Add confidence to phrase-memory DB entries/matches and propagate it through TS + Rust layers.
• Simplify pipeline phrase-memory config to autoSearchPhraseMemory, phraseMemorySimilarityThreshold, and phraseMemoryMaxResults, plus manual refresh from the Memory tab.
