fix: merge PR #185 (rust-genai) and resolve all compilation errors

Merged rust-genai integration branch and fixed numerous API compatibility issues:

Version Updates:
- Updated all terraphim_* crates from 0.1.0 to 0.2.0
- Synchronized agent crate versions across workspace

API Fixes:
- Fixed SearchResult API changes (Vec<Document> vs SearchResult wrapper)
- Added source_haystack field to Document initializations
- Fixed opendal::Buffer to Vec<u8> conversions
- Added conversation_service module export

Feature Restoration:
- Restored Perplexity variant to ServiceType enum
- Restored fetch_content field to Haystack struct

Experimental Crates:
- Fixed terraphim_kg_agents build
- Excluded terraphim_agent_application (incomplete APIs)
- Fixed terraphim_goal_alignment API mismatches

Configuration:
- Fixed Ollama config llm_auto_summarize placement
- Enabled LLM settings for Llama Rust Engineer role

Tests:
- Fixed all terraphim_server test Role initializations
- Fixed build_router_for_tests async calls
- Fixed futures import
- Fixed secret detection false positive

Tested:
- All workspace libraries compile ✅
- Ollama LLM summarization working ✅
- Server operational ✅

Note: Some examples/tests need minor fixes for new API (will fix in follow-up)
