feat(CF-1316): Add LLM metadata extraction at embedding time

Browse Source 
Extract structured metadata (topics, decisions, blockers, tools_used,
projects, issue_keys) from session summaries using Haiku at session end.
Metadata stored in JSONB column with GIN index for filtered retrieval.
session_semantic_search now accepts optional metadata filters.
